Influencing Quantities and Influence Error
1
The 60 mV DC range and thermocouple measurement are sensitive to temperature
fluctuation: For this reason, specified values are not valid 30 until minutes after
ambient temperature has stabilized.
2
Power limiting: frequency x voltage max. 6 x 10
6
V x Hz for U > 100 V
3
The accuracy specification for frequency response is valid as of a display value of
10% of the measuring range for both measuring modes with the TRMS converter
in the A AC and A (AC+DC) ranges.
4
Frequency response up to 100 kHz, > 60 kHz plus 5%
Response Time (after manual range selection)
Data Interface
Type Optical via infrared light through the housing
Data transmission Serial, bidirectional (not IrDa compatible)
Protocol Device specific
Baud rate 38,400 baud
Functions – Select/query measuring functions
and parameters
–
Query momentary measurement data
– Read out stored measurement data
The USB X-TRA plug-in interface adapter (see accessories) is
used for adaptation to the PC’s USB port.
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 sym-
bol 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
