• The instrument briefly notifies
“done”
when restores factory calibration and
returns to
measurement mode
.
To save battery, the instrument shuts down after 10 minutes of non-use in
measurement mode
and
after 1 hour of non-use in
calibration mode.
If a valid measurement was displayed before auto-shut off, the value is displayed when the instrument
is switched on. The blinking “ZERO” means that a new zero has to be performed.
One fresh battery lasts for around 750 measurements, depending on the light level.
The remaining battery capacity is evaluated at the instrument startup and after each measurement.
The instrument displays a battery indicator with three levels as follows:
• 3 lines for 100 % capacity
• 2 lines for 66 % capacity
• 1 line for 33 % capacity
• Battery icon blinking if the capacity is under 10 %.
If the battery is empty and accurate measurements can’t
be taken anymore, the instrument shows “
dead batt
dead batt
dead batt
dead batt
dead batt
”
and turns off.
To restart the instrument, the battery must be replaced
with a fresh one.
