7 Technical data
The abbreviation „i.v.” in the basic uncertainty
definition means the indicated value.
Constant voltage measurement (on the dis-
play):
* - from 6,0V for Sr. no. up to 681793
Additionally the voltage is indicated by the diode
bar for the following values: 12, 24, 50, 120, 230,
400, 690V along with the signalling of the voltage
polarization (the diode „+” or „-” is lit). The diode
indicator functions also without batteries.

Alternating voltage measurement within the
range between 20 and 400Hz (on the display):
* - from 6,0V for Sr. no. up to 681793
Additionally the voltage is indicated by the diode
bar for the following values: 12, 24, 50, 120, 230,
400, 690V along with the signalling of alternating
voltage (diodes „+” and „-” are lit simultaneously).
The diode indicator functions also without batter-
ies.
The measurement voltage frequency for the diode
bar: 15…400Hz.
