Proper PPE is required. Follow all safety procedures, wear proper PPE in accordance to NFPA 70E and follow the guidelines below and the instructions in the manual when operating the IDEAL 61-405 Fork Meter.

Follow all safety procedures, wear proper PPE in accordance to NFPA 70E and follow the guidelines below and the instructions in this manual when operating the meter with TL-757 Test Leads or equivalent.

Test Leads must be rated for the electrical environment the meter is being used in and have a voltage rating of at least the voltage of the circuit to be measured. Failure to comply can result in serious injury or death.

Before using the test leads, inspect them carefully for damaged insulation, exposed metal or bent probes. Check test leads for continuity. Do not use leads if they appear damaged.

Connect the common test lead before connecting the live test lead. When disconnecting test leads, disconnect the live test lead first.

First, rotate the function key to the NCV position. Place the jaw tip marked with NCV close to an AC outlet (or any AC conductor such as light switches or power cords) and scan back and forth across the outlet. A steady tone (buzzer) will sound, and the Red indicator LED flashes at a frequency of 3Hz simultaneously if live voltage is greater than 40VAC (50~60Hz) is detected.

To differentiate between hot and neutral in an outlet, place the NCV tab directly next to each slot in the outlet. The tone (buzzer) will sound over the slot that is energized and not on the neutral slot.

Either test lead can also be used to differentiate between the hot and neutral. Plug the red or black test lead into the V input jack on the meter. With the function switch in the NCV position, insert the probe end of just one probe into the slots on the outlet. The meter will beep and the Red LED will flash when a hot conductor is contacted.

While the NCV is a helpful function, it is ALWAYS RECOMMENDED that the operator verify that any electrical conductor is completely de-energized and that no voltage is present by measuring for voltage AND CONFIRMING THAT NO VOLTAGE IS PRESENT by using a digital multimeter and lead set and that all applicable PPE and lock out tag out procedures be followed before attempting any work on ANY electrical distribution system.

Voltages with frequencies higher than 60Hz or electrostatic charges may also be detected by the NCV sensing antenna.

When measuring current, align conductor with dash marks on meter jaws.

For DC current point the arrow (located at base of jaws) towards the load.

Use the V/Ω input terminal for the live test lead and the COM input terminal for the common test lead, connected in parallel across the AC source or DC source.

Verify the circuit is de-energized.

The meter will sense the level of resistance and beep if the resistance is less than 10 Ω to confirm that continuity is present.

Red LED will illuminate and resistance value will be displayed.

Verify the circuit is de-energized to obtain accurate measurements.

To exit Continuity and enter the Resistance mode, press the SEL Button.

To exit Resistance and enter the Capacitance mode, press the SEL Button.

To exit Capacitance and enter the Diode Test mode, Press the SEL Button.

The meter LED remains RED and the beep lasts for 1 second and then goes silent when voltages in excess of 30V are measured or when the meters voltage range is exceeded.

NOTE: This feature does not work in the Ohm, capacitor, continuity or amperage modes.

Press the Hold button on the side of the meter to toggle in and out of the data hold mode. “HOLD” appears in the lower left of the meter display when data hold is active. Use the data hold feature to lock a measurement reading on the display. Press the Hold button again to unlock the display and obtain a real-time reading.

The MAX/MIN records the maximum or minimum measured value. Press the MAX/MIN button to activate this feature and to toggle between MAX, and MIN readings. The unit will continually capture MAX or MIN values over time. Depressing the MAX/MIN button for >2 sec. exits the MAX/MIN mode.

Press the Delta (Relative) button to enter the Relative mode. The Delta symbol is displayed, and the value on the display is stored as a reference value. In the Relative mode, the value shown on the display is always the difference between the stored reference value and the present reading. Press the Delta button again to exit the Relative mode.

The meter automatically powers itself down after about 30 minutes of no use. Press any button, and the meter will wake up and display the last reading taken before power down. To Disable APO, press and hold the SEL button while turning the dial to any desired function. When APO is defeated, the “APO” will be removed from the display. Turning the meter off and back on will restore the APO default.

Press and hold the SEL button for > 2 seconds on the meter to turn the backlight/flashlight on and off. The white backlight and flashlight will remain lit for about 5 minutes before they automatically turn off to conserve battery power. Or turn the lights off by pressing the SEL for more than 2 seconds.

To avoid false readings that can lead to electrical shock and injury, replace the batteries as soon as the low battery indicator appears.

The function operation table for the IDEAL 61-405 Fork Meter is as follows:

Note: Long Press: > 2 seconds Short Press: < 2 seconds

Short Press: Circularly enter or exit the data hold mode, LCD will display HOLD symbol.

1) Short press: Circularly select the appropriate test function.

2) When in HOLD, RANGE, MAX/MIN, REL / ZERO function, Short press the SEL key will exit current function and go into the relative select function.

3) Long press: Circularly turn on or off the backlight and flashlight, default is off, Applicable to all measuring settings. The backlight and flashlight will turn off automatically 5 minutes after they are activated. Long press SEL button again to turn on the backlight and flashlight.

1) Short press the RANGE key to enter manual range mode (LCD will not display “AUTO”), and the current range, press again to enter cyclical selection range. Long press: exits manual range and enters Auto range. Switching measurement setting or restarting the unit returns the unit to the default setting.

2) In HOLD, MAX/MIN, REL / ZERO function, Short press the RANGE key to exit the current function and enter the relative range function.

1) Short press: enter “MAX/MIN” statistics mode, continuously updates the data, and you can circularly view the maximum value→ minimum value→ maximum value. Long press: exits statistical mode and returns to the normal working mode. After pressing the REL/ZERO, and then short pressing MAX/MIN, the unit will show the MAX/MIN after deducting the initial offset value.

2) When HOLD function is in use, MAX/MIN is invalid.

3) After entering the statistical mode, exit the automatic range at the same time and enter into the current range, the APO will be disabled; exit the MAX/MIN function to restore the automatic range and automatic shutdown.

4) In the statistical mode, a short press of the HOLD key will stop refreshing the statistical data. At the same time, a short press of the MAX/MIN key can review the stored data of MAX/MIN, a short press of the HOLD key exits HOLD to continue refreshing the statistical data.

1) Short press: Circularly enter or exit REL function (when entering REL function, LCD will display Delta symbol)

2) Entering the REL function, exits auto range and enters into the current range.

3) Entering the REL measurement mode does not change the actual measurable range of the current range

4) When HOLD or MAX/MIN is in use, REL function is invalid.

1) Short press: Circularly enter or exits the ZERO clearing function (when entering the ZERO function, the LCD will display the “ZERO” symbol)

2) Pressing ZERO does not affect the current automatic or manual range status. Pressing ZERO and then pressing MAX/MIN will exit the automatic range and enter the current range.

3) When HOLD or MAX/MIN is in use, the ZERO function is invalid.
