Using the device
Please observe the following basic obligations when using the device:
• Before carrying out tests and measurements, disconnect all poles of the PVgenerator from
the PVinverter. The PVgenerator must be isolated from the electric power supply! Neither
the positive nor the negative pole of the PVgenerator must be earthed!
• Make sure that all switching and disconnecting devices are open and all PVstrings are
insulated from each other.
• Please observe that the PVgenerator must not exceed the maximum open-circuit voltage of
1 000V, the maximum short-circuit current of 15A and the maximum DCpower
(P=VOCxISC) of 10kW.
• Carry out the tests and measurements only on individual PVstrings. Please observe that
the short-circuit currents (ISC) of PVstrings connected in parallel add up and might
additionally increase due to existing capacitances of the PVgenerator.
• Make sure that no power optimisers are installed in the PVgenerator. In the event of a
short-circuit, power optimisers might generate transient current peaks that significantly
exceed the specified short-circuit current (ISC) of the PV generator.
• The device may only be used in a technically perfect and safe condition. Always check the
device for damages before using it.
• The personnel must be qualified for the respective task.
• Observe relevant regulations on occupational safety and health as well as those on

4.2.1 Measured value memory
The device can store up to 200display indications. Depending on the measurement performed,
the protective conductor resistance, the open-circuit voltage, the short-circuit current, the
insulating resistance with testing voltage or the measured AC/DCcurrent are stored for each
memory location with a date and time stamp.
Storing measured values
Press the “Save”key to store the displayed measured values to the first free storage location.
Successful storage will be confirmed by the “STORE”symbol on the digital display.
Calling measured values
Press the “Measured value memory”key to recall the stored measured values with the
corresponding storage location number. The “RECALL”symbol appears on the digital display
and the storage location number is displayed.
Press the “Measured value memory”key again to switch to the next storage location and press
the “Save”key to switch to the previous storage location.
Deleting the measured value memory
Press the “Save”key and the “Measured value memory”key simultaneously to delete the entire
measured value memory.
Calling the average value
The device determines the average values of the open-circuit voltage and the short-circuit
current of the entire measured value memory and stores them in storage location0.
Switch to storage location0 to call the average values. The “RECALL”symbol appears on the
digital display and the average values of the open-circuit voltage and the short-circuit current
are displayed.
5% deviation from the average value
In case the displayed measured value deviates by 5% from the average value, the
“5%deviation”symbol flashes.
