Lightmeter LM10
8. Appendix
8.1. Power supply
The Lightmeter LM10 is provided with two batteries of type Mignon AA with voltage. The battery
compartment is located at the bottom side of LM10.
Batteries of type NiMH are recommended for frequent use of Lightmeter LM10. In accordance with
Art.-No. 510, a battery pack with two battery sets and charger is available.
For the measurement operation, the maximum operating time is of approximately 20 hours; in the
data logger mode for an interval of one minute, it is approximately seven days.
If the end of battery life is reached or the batteries are almost completely discharged, the battery
symbol in the display indicates that the batteries must be exchanged. If the supply voltage neces-
sary for the operation falls short, then the LM10 automatically turns off, wherein a regular data
recording independently ends at this point of time, if required. The LM10 gives a warning through a
periodic beep shortly before turning off.
The power supply of LM10 can be established via USB-connector with USB-power supply (Art. No.
520). When powered by power supply the batteries may remain in the device without being
charged.
If the
Auto-Power-Off
function is active, then LM10 turns off in case no button is pressed for more
than five minutes.
8.2. Maintenance
The sensors must be protected against contaminants of all types.
The device and sensors must be checked and re-adjusted by the manufacturer in case of greater
pollution and every two years.
Remove the batteries for five minutes in case of an operation error. Switch on the LM10 again.
When you keep the
Record
button pressed when switching on, all the settings of LM10 are reset.
If the problem still persists, contact Fauser Elektrotechnik.
8.3. Firmware
The firmware of the field meter LM10 is continuously being updated. Information regarding the
current firmware version is available under
