OPERATION
Power ON/OFF pushbutton
Press 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 meter automatically turns itself off if no pushbutton is pressed for ten minutes. •
Press ON/OFF key again to turn the meter off.•
Warm-up Status
When the meter is ON and READY LED is off, the sensor enters into a warm-up process. The •
warm-up time is less than 60 seconds.
When 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.
Mute Function
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. The earphone is not supplied with the GSD600.
A standard earphone will work with this unit.

6
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.
Leakage Checking
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.
BATTERY REPLACEMENT
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
Meter does not turn on
Make sure you press the ON/OFF key for about two seconds.1.
Make sure the batteries are O
K2.
Replace the batteries and try again3.
Ready LED does not turn on after 60 seconds warm up
Check the sensor contact.
If LED is still off, please return the meter for replacement or repair.1.
MAIN
TENANCE
Situations to be avoided
If silicone vapor is absorbed onto sensor’s surface, the sensor will become coated. So, avoid 1.
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 2.
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 3.
water spray
Sensor drift may occur if soaked or splashed with water.4.
Freezing water on the sensor surface may damage it or alter its characteristics.5.
Do not operate the meter under low oxygen atmosphere. The required operating oxygen is 6.
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, 1.
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 2.
even when the meter is off.
W
hen the meter is off for a long period of time, the sensor may show a drift in resistance 3.
according to the storage environment. The meter should be stored in sealed bag with clean
air.
Note:
W
hen 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 4.
such as high humidity, extreme temperature, or high contamination levels for a long time,
the performance of the meter could be affected.
