AMPROBE GSD600 (01) PDF Document

The GSD600 Gas Leak Detector features include:

• Detects methane and propane gas
• Quick to pinpoint gas leaks
• Automatic calibration when power is on
• Auto power off to save battery life
• 60 seconds warm up time
• Response time less than 10 seconds
• 5-level LED leak alarm
• 440 mm long flexible probe
• Built in earphone jack
• Mute function

The standard accessories included with the AMPROBE GSD600 Gas Leak Detector are:

• 1x Instrument GSD600
• 4x AA Batteries
• 1x Users Manual

Press the ON/OFF key for more than two seconds to turn on the meter. While the meter is on, the BAT. OK LED will stay on.

Press the ON/OFF key again to turn the meter off.

The meter automatically turns itself off if no pushbutton is pressed for ten minutes.

When the meter is ON and the READY LED is off, the sensor enters into a warm-up process. The warm-up time is less than 60 seconds. When the Ready LED is ON, the meter is ready to be used. During that period of warm-up, a special compensation circuit automatically limits the effect of the environmental changes. Any time you turn the unit off and turn it back on, it will go through the warm-up process again. Wait for 60 seconds.

The frequency of the beep will increase when the detected gas concentration becomes higher. While using the meter with the earphone, the meter will automatically be muted, allowing the user to hear the beeper through the earphone. If the earphone is not in use, the user can mute the beeper by switching the mute button to the ON position. The user then has the LED’s as the indicator and no sound.

To check for pipe leakage, proceed as follows:

• Approach the pipe slowly with the sensor pointing to the pipe.
• Repeat the procedure from the other side of the pipe.
• When the sensor is near to a leak, the LED will light and the frequency of the beep will increase.
• It takes at least 2-min for the sensor to recover after leak detection.

When the low battery LED turns ON, it is recommended to replace the batteries with new ones to ensure the accuracy of the meter. Open the battery comportment and replace the batteries with 4 new AA batteries.

Troubleshooting for when the meter does not turn on:

1. Make sure you press the ON/OFF key for about two seconds.
2. Make sure the batteries are OK
3. Replace the batteries and try again

Check the sensor contact. If LED is still off, please return the meter for replacement or repair.

Situations to be avoided:

• If silicone vapor is absorbed onto sensor’s surface, the sensor will become coated. So, avoid exposure of the meter to silicone adhesive, hair grooming materials, and silicone rubber. This situation reduces the meter’s effectiveness.
• High-density exposure to corrosive materials such as H2S, Sox, CI2, and HCL etc may cause corrosion or breakage of the lead wires or heater material.
• Second drift may occur when the sensor is contaminated by alkaline metals or especially salt water spray
• Sensor drift may occur if soaked or splashed with water.
• Freezing water on the sensor surface may damage it or alter its characteristics.
• Do not operate the meter under low oxygen atmosphere. The required operating oxygen is around 21% under ambient oxygen environment.

Situations to be avoided whenever possible:

• Light condensation under indoor usage should not be a problem for the sensor. However, if water condenses on the sensor’s surface for a time period, the sensor characteristics may drift.
• Sensor performance may be also affected if exposed to a high density gas for a long time even when the meter is off.
• When the meter is off for a long period of time, the sensor may show a drift in resistance according to the storage environment. The meter should be stored in sealed bag with clean air. Note: When the unit is not powered on for a long time, the warm-up time becomes longer for stabilization.
• Regardless of the powering state of the meter, if the meter is exposed to extreme condition such as high humidity, extreme temperature, or high contamination levels for a long time, the performance of the meter could be affected.

The specifications for the AMPROBE GSD600 Gas Leak Detector are:

Range:

Press the ON/OFF key for more than two seconds to turn on the meter. While the meter is on, the BAT. OK LED will stay on.

To ensure the accuracy, users must perform the warm-up period in clean air.

The warm-up time for the AMPROBE GSD600 Gas Leak Detector is less than 60 seconds.

If the earphone is not in use, the user can mute the beeper by switching the mute button to the ON position. The user then has the LED’s as the indicator and no sound.

While using the meter with the earphone, the meter will automatically be muted, allowing the user to hear the beeper through the earphone. The earphone is not supplied with the GSD600. A standard earphone will work with this unit.

It takes at least 2-min for the sensor to recover after leak detection.
