Resistance reading – A and B result flag (registers 506-507)
4.3
The following tables detail the result flag bytes:
bit 7 (MSB) bit 6
0 – OK not used not used
1 – the
measurement
has not
begun
* See the overview of registers 200-207, Parameter 1.
bit 7 (MSB) bit 6

4.4 Status flag readout (register 520)
The bit fields of the Status byte are explained below:
bit 7 (MSB) bit 6
not used not used not used
Result flag field A (register 506)
bit 5 bit 4
If the AutoRange full mode is disabled*
and the measurement function is
R |U = 500 V or
ISO ISO
R |U = 1000 V:
ISO ISO
0 – no underflow error (R
1 – underflow error present (R
If the AutoRange full is active*, the bit is
always set to 0.
Result flag field B (register 507)
bit 5
not used
bit 5 bit 4
0 – test 0 – no voltage ≥ 50V

R
discharging in
progress
The measurement is
stopped when AC ≥ 50 V
or DC ≥ 50 V with
reversed polarity is
detected at the test
terminals.
