Power Supply
Battery 2 ea. 1.5 V mignon cell (2 ea. size AA),
alkaline manganese per IEC LR6
(2 ea. 1.2 V NiMH rechargeable battery
also possible)
Service life
with alkaline manganese: approx. 200 hours
Battery test Battery capacity display with battery 
symbol in 4 segments:
. 
Querying of momentary battery voltage via
me
nu function.
Power OFF 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
are activated for an adjustable duration
of 10 to 59 minutes, and the multimeter
is not in the continuous operation mode
Power pack socket 
(METRA HIT AM XTRA / X-
TRA / OUTDOOR only)
If the NAX-
TRA power pack has been
plugged into the instrument, the batteries
are disconnected automatically.
Rechargeable batteries can only be
r
echarged externally.
Display
LCD panel (65 mm x 36 mm) with analog and digital display includ-
ing unit of measure, type of current and various special functions
Background illumination
Background illumination is switched off approximately 1 minute
aft
er it has been activated.
Analog
Display
LCD scale with bar graph or pointer, depend-
ing on the selected parameter setting
Scaling With 4 division lines each, 1 bar/pointer cor-
responds to 500 digits at the digital display
Polarity display With automatic switching

Polarity display “–” (minus sign) is displayed 
if plus pole is connected to “”
Measuring rate 10 and 40 measurements per second
with
the Min-Max function except for the

capacitance, frequency and duty cycle 
measuring functions
Refresh rate 2 times per sec., every 500 ms
Acoustic Signals
For voltage Intermittent signal at above 1000 V
