5.1. Batteries
Battery condition is currently displayed; see the battery condition mark in the left side
of display. Fully dark battery mark presents full-capacity batteries. Follow the battery
condition even during carrying out measurements. Results obtained with low battery
voltage (the results may be incorrect) will be marked with
bat
mark after finishing the
measurement.
Replace all four batteries, when the battery mark is empty in static mode (no
measurement is running) or when the battery mark trips to empty frame just
temporarily, while a measurement is running!
Nominal power supply voltage is 6 Vd.c. Use four 1,5 V alkaline batteries, type IEC
LR14 (dimensions: diameter = 26 mm, height = 50 mm).
