Two safety sockets
These sockets of diameter 4 mm and 19 mm gap, receive the set of leads with prods for measurements of
voltages and powers.
Communication output (DATA OUT)
This output allows connection to a PC or a printer, via the RS232 optical link.

3.4 SOUND SIGNALS

The clamp has a buzzer which emits a sound signal at three different frequencies and of three different lengths.

- Respect the safety precautions
- Do not use the clamp on cables or conductors at a voltage of more than 600 V RMS (See Ch 5.3 Limits on voltage
measurements)
- Do not use the clamp on currents above 1000 A RMS (see Ch 5.2 Limits on current measurements)
- Ensure the correct positioning of the switch before any measurement
- Ensure that the jaws are correctly closed
- Use the safety leads (IEC 1010) supplied with the clamp.

4.1 SWITCHING ON

By selecting the main function V AC/DC, A AC/DC, W AC/DC, W AC/DC 3Ø 3C or PRGM (communication output) with
the switch, all the segments and symbols appear for 1 second on the display and a "validate beep" is emitted.
NB : The initial configuration of the clamp is: auto off - buzzer on - AC + DC mode.
This configuration can be modified, by pressing one of the function buttons when switching on
(see Ch 4.3. Configurations).
4.2 AUTO / MANUAL OFF
The clamp switches off automatically after 10 minutes of operation in the following conditions :
- buttons not pressed
- selector switch not turned
- permanent operation switched off
- no current or programmed output
The purpose of this function is to economise the battery, when you forget to reset to the OFF position after
measurements. The clamp emits a serie of 5 beeps before going into "Sleep" mode.
