MENU Key: Enters the Main Menu to select a function. Pressing MENU also cancels the current measurement or setting and returns to the Main Menu.

START/HOLD Key: Starts and stops calculations and/or measurements. It also functions as a hold key during measurements.

▲ ▼ Navigation Keys:
1. In Normal Mode, these keys allow you to select the time constant (TC) of 1, 5, or 10 seconds. TC1 displays the instantaneous value every second, TC5 displays the moving average for 5 seconds, and TC10 displays the moving average for 10 seconds.
2. In the Main Menu, these keys scroll in the desired direction.

MODE Key: Selects the measurement mode. The available parameters, depending on the connected probe and main body model, cycle in the following order: Air Velocity/Air Temp/Humidity → Pressure → Air Flow/Air Temp/Humidity.

SET Key: Executes the selected item.

Follow these steps to install or replace the batteries:

1. On the backside of the body, press down on the battery cover.

2. Slide the cover until it stops.

3. Lift the cover away from the body.

4. Insert six (6) AA size batteries according to the indicated polarity chart. All batteries must be of the same type. Do not mix different types of batteries.

5. Put the cover back on by reversing the above procedure.

Note: Batteries CANNOT be recharged by the AC adapter.

The following types of AA batteries can be used:

• Manganese

• Alkaline

• Ni-Cd

• Ni-MH

Ensure the power is turned OFF before connecting or disconnecting the probe.

1. Align the connector of the probe or probe cable with the probe terminal on the body. When connecting the probe directly, make sure the probe number faces towards the front side of the main unit.

2. Line up the connector and the terminal and gently push until it clicks.

Important: DO NOT FORCE the connector in, and DO NOT ROTATE the probe/probe cable once it is connected, as this may cause serious damage.

Ensure the power is turned OFF before connecting or disconnecting the probe.

1. Lightly lift the locking ring of the probe/probe cable.

2. Pull the probe/probe cable out vertically while holding the lock ring up.

Important: DO NOT rotate the connector while it is connected to the main body, as this may cause serious damage.

The power switch is located on the side of the instrument.

• To Turn On: Move the switch to the “|” position.

• To Turn Off: Move the switch to the “O” position.

When you turn the power on with the probe connected, a test screen with the Kanomax logo, model, and firmware version will display for a few seconds before switching to the Normal Mode screen.

“NO PROBE!” Warning: If the probe is not connected properly, this warning will be displayed. Turn the power off and check the probe connection.

Annual Calibration Reminder: A year after the last calibration, a notice to perform the annual calibration will be displayed. The screen will switch to normal measurement mode after 10 seconds or after any key is pressed.

Battery Level Indicator: This icon on the screen shows the remaining battery level. The consumption rate depends on the measured air velocity. When the batteries need to be replaced, the indicator will start blinking. If a high velocity is measured while the indicator is blinking, the screen may freeze. When the locked status icon [X] is displayed, all functions are locked. Turn off the power and replace the batteries.

Air Velocity

• For directional probes (MODEL 6531/6541/6561), make sure the direction mark is facing into the airflow. If unsure of the direction, slowly rotate the probe to find the maximum velocity reading.

• Omnidirectional probes (MODEL 6533/6542/6543/6551/6552) have a horizontal, 360-degree dynamic characteristic.

• Ensure that both the air velocity sensor and temperature compensation sensor are evenly exposed to the airflow under the same conditions.

• In environments with rapid air temperature changes, allow the reading to stabilize for at least 20 seconds before starting the measurement to let the probe acclimate.

Air Temperature

• The response time for temperature is faster with higher wind speeds. The normal response time is approximately 30 seconds at 1 m/s air velocity. Wait for the reading to become stable.

• When there is no airflow, the temperature reading may be higher than actual due to heat from the air velocity sensor. It is recommended to slowly wave the probe to create approx. 0.1 m/s airflow for accurate readings.

Humidity

• In extremely high humidity or with rapid temperature changes, readings may be higher than actual due to condensation on the sensor. If this occurs, allow the probe to dry in an atmosphere with 40%RH or less for 24 hours.

Pressure (for applicable models)

• Do not expose the pressure sensor to more than 75kPa of pressure.

• The operating temperature for measuring pressure is between 5°C and 40°C (41°F and 104°F).

• Perform a zero adjustment before measuring pressure. Leave both pressure ports (+) and (-) open during zero adjustment.

• The zero adjustment range is -0.5 to 0.5 kPa. An error message will display if the reading is outside this range.

If the LCD display is too dark or too light, you can adjust the contrast.

1. Open the battery cover on the back of the unit.

2. Locate the contrast adjusting dial at the bottom of the battery compartment.

3. Use a precision screwdriver (-) with a tip size of 0.9 to 1.5mm to turn the dial.

• Turn the dial clockwise to darken the LCD.

• Turn the dial counterclockwise to lighten the LCD.

Dust or particles on the velocity sensor can lead to less precise readings. Regular cleaning is recommended to maintain accuracy.

Procedure:

Clean the sensor by soaking it in water in an ultrasonic cleaner for 10 to 20 seconds. Do not soak it for too long, as this increases the risk of damaging the coating. Use only water for cleaning.

CAUTION:

• When cleaning, make sure the power is turned OFF.

• Make sure the sensor is completely dry before turning the instrument ON.

• For probes with a humidity sensor (MODEL 6531/6533), DO NOT let the humidity sensor come into contact with water. If it gets wet, let it air dry in an environment with less than 40%RH for more than 24 hours.

• NEVER use alcohol or any other organic fluid, as this will cause permanent damage to the humidity sensor.

• After cleaning, DO NOT place the sensor in an upward position until it is completely dry, as residual water could damage the sensor. You can use cool air to help dry it.

The battery may be inserted with the wrong polarity. Turn off the power and re-insert the batteries correctly according to the polarity markings in the battery compartment.

The display contrast may not be set up properly. Locate the contrast adjustment dial inside the battery compartment and adjust it with a small screwdriver.

A flashing battery level indicator means the battery is low. You should turn off the instrument and replace the batteries.

This message indicates that the probe is not connected or not connected properly. Turn off the instrument and check the connection of the probe to the main body.

This indicates that the measurement is outside the measuring range of the instrument. The instrument must be used within the range stated in its specifications.

This can be caused by a few issues:

• The probe or the probe cable is not connected properly. Check the connection between the probe and the probe cable, and the cable to the main body.

• The probe or the probe cable may be damaged. If the connection is secure, contact your local representative for repair or replacement.

The probe might not be facing into the wind correctly. For directional probes, make sure the wind direction indicator mark is facing directly into the airflow.

The CLIMOMASTER cannot measure the correct temperature with no wind (less than 0.1m/s of wind) because of heat generated by the velocity sensor itself. To get an accurate reading, slowly wave the probe to create a small amount of airflow.

The instrument’s Time Constant (TC) setting may be too high. In NORMAL mode, you can set the TC to a shorter value (e.g., TC1 for a 1-second response) to make the readings more responsive.

This display indicates that the duct information (shape and size) required to calculate the flow rate is not stored or selected. You must go to the DUCT TYPE menu and register the duct information.

There are several possible causes:

• Printer not connected properly: Confirm the printer connection.

• Baud Rate mismatch: Check that both the instrument and the printer are set to the same Baud Rate.

• Incorrect printer/cable: Make sure to use the optional printer (Model DPU-S245) and printer cable (Model 6000-31).

• Connection procedure: Ensure you connect the printer to the printer port, then turn on the instrument first, and then the printer.

The display is not frozen. First, press the START/HOLD key to hold the display. Then, press the MODE key to print out.

• Connection: Confirm the USB connection is secure.

• Baud Rate: The Baud Rate might not be set properly. Check that both the instrument and the PC’s terminal software are set to the same Baud Rate.

• Command: Confirm you are using the correct communication command (e.g., in Hyper Terminal).
