also possible)
with alkaline manganese: approx. 200
hours
Battery capacity display with battery
symbol in 4 segments:
Querying of momentary battery voltage via
menu function.
Multimeter is switched off automatically:
– If battery voltage drops to below prox. 1.8 V
– If none of the keys or the rotary switch
If the NA X-TRA power pack has been
plugged into the instrument, the batteries
are disconnected automatically.
Rechargeable batteries can only be
recharged externally.
LCD scale with bar graph or pointer, depend-
ing on the selected parameter setting
With 4 division lines each, 1 bar/pointer cor-
responds to 500 counts at the digital display
With automatic switching

“OL” is displayed for ≥ 60,000 counts
“–” (minus sign) is displayed
if plus pole is connected to “⊥”
