4 Intended use
5
Do not allow the sensor to come into contact with moisture or acids, as it will
react cross-sensitively.
4 Intended use
The testo 316-1-EX is a gas leak detector for the short-term detection of leaks in
gas systems in potentially explosive atmospheres of the class
ATEX II 2 G Ex ib IIC T1G according to Directive 2014/34/EU (ATEX).
The following substances can be detected:
Methane CH4
Propane C3H8
Butane C4H10
Hydrogen H2
The instrument is not suitable for precise measurement of the gas
concentration.
ATTENTION
Explosive limits of flammable substances
A flammable substance in the air has a lower explosive limit (LEL) and
an upper explosive limit (UEL).
The air/gas mixture is flammable anywhere between these two limits,
potentially leading to an explosion (critical range).
Below the LEL, the mixture is too lean for an explosion, and above the
UEL it is too rich (non-critical range).
The explosive limits depend on the substance:
-Methane CH4: LEL 4.4 vol.% / UEL 16.5 vol.%
-Propane C3H8: LEL 1.7 vol.% / UEL 10.9 vol.%
-Butane C4H10: LEL 1.4 vol.% / UEL 9.4 vol.%
-Hydrogen H2: LEL 4.0 vol.% / UEL 77.0 vol.%
ATTENTION
Restrictions on the field of use
-Do not use the instrument as a monitoring instrument for personal
safety! The instrument is not protective equipment!
-Do not use the instrument as a gas analyzer! The sensor detects
almost all combustible gases alike.

6 First steps
6.1 Getting to know the product
6.1.1 Switching the instrument on and off
Switching on
Only switch on the instrument in fresh air, since automatic zeroing is carried out
when the instrument is switched on. The ambient temperature and ambient
humidity during zeroing should correspond to the ambient conditions at the
measuring location. If necessary, zero again manually at the measuring location
(switch off and on again).
If the unit is not used for a prolonged period of time, the sensor will
become contaminated. Particularly if the instrument has not been in
operation for a prolonged period of time (> 2 weeks), it should be left
switched on for a while before being used. The longer it has not been in
operation, the longer this additional warming-up phase should be.
Please note that the instrument switches itself off by default after 10
min of inactivity.
1
Press and hold down (1 sec) the On/Off key.
Warm-up phase (HEAT)

The instrument starts up. With regular use, the warm-up period takes
approx. 20 sec and is symbolized by the text "HEAT" and a
countdown.
As long as the sensor LED is flashing orange, the instrument is not
ready for use.

Following the warm-up period, the measurement view is displayed.
Self-cleaning (CLN)

If the sensor is dirty, the warm-up phase is followed by the sensor
cleaning phase. This usually happens when the instrument has not
been used for several days. The self-cleaning is symbolized by the text
"CLN" and a countdown.
Switching off
CAUTION
Caution! Risk of burns due to hot sensor head after prolonged
operation.
-Before touching the sensor head or packing the instrument: switch
instrument off and let the sensor head cool down.

6First steps
8
1
Press and hold down (1 sec) the On/Off key.

The instrument is switched off.
Auto OFF
After 10 minutes of inactivity (no user input, no gas concentration above the
warning threshold), the instrument switches itself off. The switch-off is signalled
beforehand by an alarm sound, red flashing of the sensor LED and a 10 sec
countdown.
You can prevent the instrument from switching off by pressing any key within 10
seconds.
Enabling/disabling the Auto-OFF function:
1
Press the Sound and UNIT keys simultaneously for 1 sec.

Enabling/disabling is confirmed by "AOFF ON" or "AOFF OFF".
6.2 Establishing a Bluetooth®connection
The instrument can be connected to the testo Smart App via
Bluetooth®connection.

The gas leak detector is switched on.
6.2.1 Establishing a Bluetooth®connection to the
testo Smart App
To establish a connection via Bluetooth®, you need a
tablet or smartphone with the Testo Smart App already
installed on it.
You can get the App for iOS instruments in the App Store
or for Android instruments in the Play Store.
Compatibility:
Requires iOS 12.0 or later/Android 6.0 or later,
requires Bluetooth®4.2.
1
Open the testo Smart App.

The app automatically searches for Bluetooth®devices in the vicinity.
2
In the Bluetooth menu, check whether the required instrument is
connected.
