also possible)
Service life With alkaline manganese: approx. 200 hrs.
Battery indicator Battery capacity display with battery sym-
bol in 4 segments: .
Querying of momentary battery voltage via
menu function.
Power OFF function The multimeter is switched off automati-
cally:
– If battery voltage drops to below
approx. 1.8 V
– If none of the keys or the rotary switch
are activated for an adjustable duration
(10 to 59 min.) and the multimeter is not
in the continuous operation mode
Power pack socket
If the NA X-TRA power pack has been
plugged into the instrument, the installed
batteries are disconnected automatically.
Rechargeable batteries can only be
recharged externally.

LCD panel (65
mm x 36 mm)
with display of up
to 3 measured
values, unit of
measure, type of
current and vari-
ous special functions.
Background illumination
Background illumination is switched off approximately 1 minute
after it has been activated.

connected to “”
Measuring rate 10 or 40 measurements per second
with
the Min-Max function except for the capaci-
tance and frequency measuring functions
Refresh Rate 2 times per second, every 500 ms
Acoustic Signals
For voltage Above 600 V in the 600 V range: intermit-
tent (250 ms on, 250 ms off)
For current – Above 10 A: intermittent signal
– Above 16 A: continuous signal
– For displayed temperature > 50 °C
