testo 316 - 1
Instruction manual
Monitoring instrument to detect gas leaks.
The testo 316-1 detects even the smallest leaks of combustible gases in pipelines, flanges and
screw connections etc. The bendable probe stem has no problem reaching even inaccessible points.
Its wide range of applications makes the gas leak monitoring instrument indispensable for every
professional.
This Instrument is not designed to operate while wet or in an environment of
Observe maximum storage and transport temperature and maximum operation temperature
(e.g. protect measuring instrument from direct sunlight)!
Do not use testo 316-1 in enclosed rooms where gases have gathered to form an explosive
Ensure that the gas concentration does not exceed the lower explosion limit of gas mixtures by 20%.
The alarm limits are adjusted downward when the sensitivity is set in a gas environment.
Always carry out a function test prior to gas leak detection.
Warranty no longer applies in the case of inexpert handling or if force is used.

mixture.
Set sensitivity of sensor in fresh air.
Switching on
- Turn control button
- Warm-up phase of sensor begins
- LED is red
- Alarm signal sounds
- Warm-up phase max 30 seconds
- LED is green
- Alarm signal off
Ready to operate
- No alarm signal
- LED is green
Setting sensitivity in fresh air
- Turn control button to the right until the sound
signal is heard
- Turn the control button to the left until the
sound signal stops.
Function test
- Expose sensor to a combustible gas e.g. from a
know leak point in the pipeline or from a butane
(gas) lighter, for a period nor exceeding 10 sec.
- If the sensor does not react (no alarm), the
instrument should be considered as defective
and must not be used. Return the unit immediatly to the nearest Test service point for
repair.
Detecting leaks
- Sound signal when gas is escaping
- Signal becomes quicker as concentration increases
- Alarm > 200 - 10000 ppm
- LED changes from green to yellow
- Warning sound
- Alarm > 10000 ppm
- LED changes from yellow to red
- Warning sound
Low Batt Signal
If during use the LED switches off and a one sec cyclic audible signal is obtained, replace the
battery within 15 min for continued working.
Changing the battery
- Open housing screw (rear of instrument).
- Insert 9 V block battery. Observe polarisation.
- Close housing.
Note on disposal: Dispose of empty batteries responsibly. Batteries should be placed in plastic
bags to avoid short-circuits.
