3. Instructions
1. Press the button to turn the unit on.
2. The LED will ash orange for a short moment to indicate auto-reset,
afterwards the unit will begin beeping and ashing green.
3. To reset the unit to the existing level of ambient SF6 or alternative
gases, press and release the button. The LED will ash orange briey
to indicate the reset. All levels of SF6 or its alternative gas less than
the reset level will be ignored.
4. Unit turns on in the low sensitivity level, which is adequate for most
leaks. Press the button twice (double-click like a computer mouse).
The LED will fade from red to green and a sweeping sound eect of
low to high pitch will be heard. The sensitivity is now set for 3g/year
(0.1oz/yr). This mode should only be used for looking for leaks of less
than 14g/year (0.5 oz/yr).
5. Double click again to change back to low sensitivity.
6. Move the probe towards a suspected leak at a rate of less than 2
inches (50 mm) per second, no more than ¼ inch (5 mm) away from
the suspected source.
7. If a leak exists, the sound will increase in rate and pitch and the LED
will start ashing rapidly.
8. To turn the GPD-1000 o, press and hold the button for 3 seconds.
4. Features
If the sensor is damaged, a sweeping alarm and a red-green ash will
indicate the problem.
A ashing LED during normal operation also reects the battery level:
■
Green: batteries are fresh
■
Orange: batteries should be changed
If the batteries are nearly empty, the LED will turn solid red and a
two-tone alarm will be noted for 5 seconds, before GPD-1000 will power
itself o.
If the unit is left on unattended, it will automatically turn o after about 5
minutes to conserve batteries.

4. Slide battery cover back into place.
6. Sensor
A GPD-1000 sensor will last between 25 and 30 hours of continuous use.
A failed or failing sensor will be indicated in one of the following ways:
1. Unstable or erratic operation of the unit and many false alarms, even
in pure air.
2. A continuous “siren” sound.
7. Sensor replacement
In either case, replacement of the sensor is necessary:
1. Turn the power o.
2. Locate the replacement sensor in the battery compartment.
3. Unscrew (turn counter clockwise) the old sensor from the end of the
probe.
4. Screw (turn clockwise) the new sensor into place.
8. Maintenance
The GPD-1000 should provide years of service with little maintenance
aside from changing batteries and sensors. The case may be cleaned
