Measurement is running, consider displayed
warnings.
Warning! A very high and dangerous voltage is /
will be present on the instrument output!
The instrument automatically discharges tested
object after finished insulation measurement.
When an insulation resistance measurement
has been performed on a capacitive object,
automatic discharge may not be done
immediately! The warning symbol and the
actual voltage are displayed during discharge
until voltage drops below 30 V.
WARNING
A high voltage is / will be present on the
instrument terminals!
(High test voltage or PV string voltage).
Unstable irradiance or too low irradiance
(Irr < Irr_min).
Calculation to STC is not possible.
Uoc .
Check module type and number of modules.
DC+ and DC- connections are reversed.
AC voltage is detected on measuring terminals.
The instrument is overheated. The
disappears.
Test leads resistance in R low measurement is
not compensated.
Test leads resistance in R low measurement is
compensated.
