Note:
The Communication settings of Powermeter must be following:
Source = RS232
Baud Rate = 9600
Select
INVERTER
sub-function using the function selector keys and
/
keys.
Be sure that the EurotestPV Lite instrument and Powermeter are connected via
serial cable or Bluetooth.
Connect
universal PV test lead or PV safety probe and DC current clamp to the
EurotestPV Lite instrument (see figures 5.20 to 5.22).
Connect
voltage test leads and AC current clamps to the Powermeter.
Connect
voltage test leads to L1, L2, L3 and N at the output side of the inverter
(see figures 5.20 to 5.22).
Connect
accessories to the PV system (see figures 5.20 and 5.22).
Check input voltages on the instrument and measurement results on the
Powermeter (best to be in
Power
measurements
menu).
Press the
TEST
key to perform the measurement. Results from both instruments
are displayed on the EurotestPV Lite screen. A.C. measurement results in detail
are displayed on Powermeter also.
Store
the result by pressing the
MEM
key (optional).
