LOW BATTERY WARNING AND BATTERY REPLACEMENT

HWhen the battery has run down and its voltage has reached the limit value of 7.2 Volts, the symbol appears permanently on the display and an alarm beep sounds at regular intervals of about 15

seconds. In these conditions the battery should be replaced as soon as possible.

If you continue to use the instrument and the battery voltage falls as low as 6.5V the instrument is no longer able to ensure correct measurement.

AFTER CHANGING THE BATTERY YOU MUST UPDATE THE CLOCK AND THE SET PARA- METERS.

To change the battery turn the instrument retaining screw in an anti-clockwise direction. After repla- cing it (with an ordinary 9V alkaline battery) close the instrument, inserting the tag into the slot pro- vided, and turn the screw in a clockwise direction.

The stored data will not be lost even if the instrument remains without batteries as long as the working routines have been completed.

Ensure that the instrument is switched off before changing the battery.

The symbol Happears fixed to indicate that the battery is low. This indication prevails over all the other signals which make use of the symbol H. In RCD function the symbol Hflashes at a fre- quency of 2 Hz. In Auto Power Off function the symbol Hflashes at a frequency of 1 Hz. The fla- shing of the RCD function prevails over the flashing of Auto Power Off.
