measuring unit.
* Press the Unit A or B key to select the temperature measuring unit in °C or °F.
4. Switching off the instrument.
* The instrument is switched off by pressing the ON/OFF key.
* Because of the Auto Power Off function the instrument may switch itself off during measure-
ments. In this case press the ON/OFF key to switch it on again.
* The instrument usually switches off automatically after 8 minutes of inactivity, with the following
exceptions:
a) Instrument in RCD status.
b) Instrument in Auto Power Off Disabled status.
In these two cases the instrument switches off only when the ON/OFF key is pressed.
c) Instrument during unloading of stored data.
d) Instrument during Serial Output of immediate data.
e) Instrument in storage function.
In the last three cases the instrument switches off automatically 8 minutes after the low
battery warning and interrupts storage and unloading of data.
When it switches on again there are two possibilities:
1. If the battery is definitively low, even when the instrument switches on again LOU appears on
the display together with the battery symbol.
The PROG key (P1+ENTER) enables the activation of the unloading of stored data even
when the battery is low.
2. If the battery has had time to recover and when the instrument switches on its charge seems,
even just a little, higher than the minimum value, LOU appears on the display without the bat-
tery symbol for a short period of time (about 4 seconds), after which the instrument returns to
normal operation; this is to remind the user that the instrument was previously in storage func-
tion and that this procedure was interrupted by the low battery warning.
5. Various operations.
* For operations such as HOLD display, relative measurements, RCD storage, DATA CALL,
Serial Output, storage in the internal memory, unloading of stored data, erasing of the internal
memory, setting of the working parameters, see the description of the instrument keyboard.
Attention when using the keyboard
The use of the keys is relatively simple, but care must be taken to avoid setting it by mistake in an
undesired mode. Ensure that HOLD, RCD, REL, MAX, MIN, MED, Serial Out/Memory are not
displayed during normal operation.
