Batteries
The instruments are powered by 6 batteries type MN 1500 LR6, 1.5 V. The battery compartment is
located at the back and fastened by two screws. Pull off the protective cover to reach the screws.
The Battery test on the setup menu shows the present battery voltage. A low battery warning is
given at 5.1 V. At this stage, only ongoing data transmission works, while the display shows
”Battery low”.
Memory and clock are protected for approx. 24 hours by a capacitor. If you replace the batteries
within that time, you will not lose any data.
The battery life depends on how the instrument is used. Full power is only consumed while a
reading is in progress: from pressing the M key until a measured value is displayed.
Battery life (with high effect cells , backlight off) is about 1 year with power off, else specified as
follows:
Typical readings: 5000 measuring points, using several techniques/point. This is based on an
average measuring time of 1 min./point, without backlight. A single measure-
ment takes approx. 2 - 10 s, here the calculation is based on 10 seconds/
measurement.
Continuous read: At least 50 hours.
Before long-time storage, keep in mind to remove the batteries.
