Internal Measured Value Storage
Memory capacity
16 MBit for approx. 300,000 measured values with indication of date and time

Power Supply
Battery
2 each 1.5 V AA batteries, alkaline
manganese per IEC LR6 (2 each 1.2 V
NiMH rechargeable batteries also possible)

Service life
With alkaline manganese: approx. 120 hrs.

Battery indicator
Battery capacity display with battery symbol in 4 segments.
Querying of momentary battery voltage via menu function.

Power OFF function
The multimeter is switched off automatically:
– When battery voltage drops below
approx. 1.8 V
– If none of the keys or the rotary switch
are activated for an adjustable duration
of 10 to 59 min. and the multimeter is
not in the continuous operation mode
(assuming the instrument is not set to
power measurement or mains analysis)

Power pack socket
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.
Power pack voltage: 5.1 V ±0.2 V

Display
Background Illumination
LED fiber-optic background illumination is switched off approx. 1
minute after it has been activated. If necessary, automatic
deactivation of background illumination can be disabled with the
appropriate parameter setting or via the interface.

Overflow display
“OL” is displayed as of 61,000 + 1 digits

Polarity display
“–” sign is displayed if plus pole is
connected to “⊥”

Sampling rate
10 or 40 measurements per second with
the Min-Max function except for the
capacitance, frequency, duty cycle and
power measuring functions, 2000
measurements per second for fast DC
measurement

Refresh rate
V (DC, AC+DC), A, Ω,
EVENTS AC/DC, count 2 per second
