BATTERY MANAGEMENT
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” and turns off.
To restart the instrument, the battery must be replaced with a fresh one.
• Turn the instrument off by pressing ON/OFF.
• Turn the instrument upside down and remove the battery cover by turning it counterclockwise.
• Extract the battery from its location and replace it with a fresh one.
• Insert back the battery cover and turn it clockwise to close.
