Operating manual GPD 3000
Application
The gas detector GPD 3000 is designed to search or and locate gas
leaks in pipes in interior and exterior areas.
The GPD 3000 is the result o our many years o experience combined
with the newest technology.
Thanks to the very simple operation o the GPD 3000, anybody may
locate gas leaks without special instruction.
The size and design o the GPD 3000 light make it the ideal instrument
or itters and emergency repair teams.
The movable sensor head permits measurement in places di icult to
reach.
Depending on the measurement tasks, the GPD 3000 will indicate
correctly di erent types o gases, since it o ers the possibility to adjust
indication or various gases (methane, propane and hydrogen).
The ollowing application areas can be covered with the GPD 3000
Gas type Ignition temperature

Propane 470 T1 / IIA
Hydrogen 560 T1 / IIC
See EN 61779 Table A.1
IMPORTANT: Obser e the yearly calibration cycle.

Unit ppm, Vol.%
Unless mentioned otherwise, the ollowing units re er to methane (CH4).
Lique ied petroleum gas usually consists o more than 90% methane.
The unit ppm refers to olume:
1 ppm = 1 cm3 100% gas distributed in 1 m3 o surrounding air
10 ppm = 10 cm3 100% gas distributed in 1 m3 o surrounding air
The unit Vol.%:
0,1 Vol.% = 1 dm3 100% gas distributed in 1 m3 o surrounding air
1 Vol.% = 10 dm3 100% gas distributed in 1 m3 o surrounding air
Con ersion factors:
0,01 = 10 = 0,00001 = 1/100
0,1 = 100 = 0,0001 = 1/10
1 = 1.000 = 0,001 = 1
10 = 10.000 = 0,01 = 10
100 = 100.000 = 0,1 = 100
1000 = 1.000.000 = 1 = 1000
1 = 0,0001 = 1 cm³
10 = 0,001 = 10 cm³
100 = 0,01 = 100 cm³
1.000 = 0,1 = 1 dm³
10.000 = 1 = 10 dm³
100.000 = 10 = 100 dm³
1.000.000 = 100 = 1 m³

Operating manual GPD 3000
Gas sensor
The sensor head contains a sensitive gas sensor, which reacts to
almost all combustible gases. Calibration o the instrument is done with
methane, and it calculates the corresponding values or propane and
hydrogen during the calibration process.
To ensure the instrument’s high reliability, you should avoid exposing
the sensor to dirt or moisture. This could cause a loss o sensitivity or
even destroy the sensor.
Gas sensors which are stored over a longer period o time loose their
unctioning point. This is due to “pollution” (binding o oxygen) on the
sensor sur ace and can not be avoided with putting them to work. For
this reason it is advised to put the instrument to work regularly (every 2
to 3 days) and let it run or about 15 minutes. This way you don’t risk
having to wait when you want to use the instrument. A measurement
signal indicates the end o the warm-up time, which may take up to 45
minutes.
To eliminate dust on or inside the sensor cover, unscrew it and clean it
with compressed air as shown in the ollowing illustration.
Important Information off sensor!
The sensor is highly corrosive environment to concentration o H2S
hydrogen sulphide, SOx sulphur oxide, Cl2 chlorine, HCL hydrogen
chloride. This leading to corrosion or break o the wires or heater
material.
Furthermore the sensor may not be detected with alkaline material, salt-
water or water. This determine very high dri t-per ormance o the sensor
(zero point stability). Dampness sensor skills under e ect o rost
breaking and destroyed.

Measurement range
The GPD 3000 o ers the possibility to adjust the indication or di erent
types o gases.
Howe er, the GPD 3000 can’t be used as an analytical instrument,
since it detects almost all combustible gases in the same manner.
Gas type Measurement range Comment
Methane 0 ppm up to 2,5 Vol% 2,2Vol% correspond to
50% LEL
Propane 0 ppm up to 1,0 Vol% 50% LEL
Hydrogen 0 ppm up to 2,0 Vol% 50% LEL
This option allows adjusting your indication or di erent kinds o gases.
I you are working on natural gas installations, it is recommended to
measure using the methane measurement range. To work on an
installation ed with propane or hydrogen, you can select the
corresponding measurement range.
As the concentration increases, the requency o the acoustic signal will
also increase, until reaching a constant sound with the maximum range.
When measuring, please take into account that methane and oxygen
are lighter than air and will rise. For these gases, measure above o the
pipe or the supposed leak.
Important notice for propane!
Since propane is heavier than air, when searching or leaks also begin
measuring the concentration on the ground, and then continue the
search underneath the pipe.

Turning on the GPD 3000
As soon as you turn on the GPD 3000 with the On/O switch, the warm-
up time starts. The sensor requires this time to reach the working
temperature.
During the warm-up time, certain unctions o the instrument are
checked. The display will be showing the available sensor ( or the ppm
measurement range) and the LED (green and red) light-up alternating.
A terwards the con iguration or gas type, language and battery state
are shown.
The warm-up time will be done when the readiness LED lights-up. In
the ready state a short signal is heard every 20 seconds, indicating that
the instrument is ready to measure. Now you can start measuring.
Zero point
The zero-point is set automatically a ter the warm-up time, as soon as
the GPD 3000 is ready. This means the GPD 3000 has set the available
surrounding air as zero point.
With the instrument turned on, you may set the zero manually striking
the zero point key, so the present measured value is determined as
zero point.
When the GPD 3000 measures a value below the set zero point, it will
indicate this by means o the blinking readiness LED. Now the GPD
3000 will very slowly counteract this tendency. However, you can also
set the zero point manually by striking the zero point key.
The range, which the GPD 3000 will accept as zero point, is limited; this
means, or instance, that you can’t „suppress“ a concentration o 1Vol%
by striking the zero point key.
Turn light on/off
Short function
When the Light unction is activated in the menu, you can turn the light
on and o by striking the zero point key (until a signal sound is heard
and the display shows LIGHT).
This unction will not be available when it is not activated in the menu
(YES).

Energy supply
The GPD 3000 uses to regular AA batteries. You can use batteries or
rechargeable accumulators. To change the batteries or accumulators,
open the battery compartment with the supplied Allen wrench.
Working time is up to 10 hours.
When the Low-Batt message appears in the display, it indicates that the
batteries are almost empty. You should be changing them.
Please do not use low quality batteries or accumulators, since the
operating time will be considerably shorter.
