BATTERY REPLACEMENT
When the battery level is low, “ BATT“ tag is displayed blinking
on the LCD to advise the user that approx. 1 hour of working time
is left.
It is recommended to change the batteries as soon as the
battery indicator blinks.
To replace the batteries, follow the next steps:
• Turn OFF the instrument.
• Open the battery compartment cap (located on the top of the
instrument).
• Remove old batteries.
• Insert three new 1.5V AAA batteries in the battery compartment,
following the instructions on the rear of the instrument.
• Reattach the battery compartment cap.
The instrument is provided with the BEPS (Battery Error
Prevention System) feature, which automatically turns the
instrument off when the batteries level is too low to ensure
reliable readings.
At start up the display will show “
0 % BATT” message for a
few seconds, then the instrument automatically turns off.
