5.1 Voltage Measurement
Never apply voltages exceeding 440V AC/DC to
input sockets.
When switching on or changing to VAC/DC
measurement range, „AC" is automatically sel-
ected.
5.1.1 AC, f, DC Voltage and Frequency
Measurement
" Select measurement range „VAC/DC, f" by
means of measurement range selection switch
(24).
"
Connect test leads to EUT.
"
Read measurement result on display.
AC voltage is displayed in the large result field
(12), frequency in the small result field (14).
If voltage exceeds 440V, „>440V" is displayed
in the large result field. Should this occure im-
mediately disconnect the test instrument from
the EUT.
If the frequency value is outside 10Hz ... 99,9Hz
range, „---„ is displayed in the small result-
field. This indication is also displayed on the
screen if the AC voltage is extremely low.
Measurement results may be stored by pres-
sing the key „Store" (26).
5.1.2 DC Voltage Measurement
" Select measurement range „VAC DC, f" by
means of measurement range selection switch
(24).
"
Select DC Voltage via key „Display" (32).
"
Connect test leads to EUT.
"
Read measurement result on display.
If voltage exceeds 440V, „>440V" is displayed
