Connecting a PC

Caution: before you can control the PVPM1000C from a PC

with PVPM.disp it is necessary to select the menu option

“transfer” on the PVPM1000C. Otherwise the PC can not

access the device.

4.5 Connecting the Solar Generator

Important: during a measurement the solar generator to be

measured must be disconnected from all other devices like

batteries, inverters or loads. The PVPM1000C will make a short

circuit to the solar generator for some seconds and it might be

damaged by connected batteries or load capacities in the

inverter!

Connect the measuring device properly to the solar generator

using the cables delivered with the measuring device. The plus

pole is marked RED, the minus pole is marked BLACK! When

connected wrong (exchanged polarity) the solar generator is in

short circuit through the in PVPM1000C integrated safety diodes

(no measurement of current possible). This condition must not

be kept for more than one minute, else the measuring amplifier

may overheat.

it is important, that all 4 plugs of the 4-wire-measurement are

connected properly by the delivered 4-wire-cable or (if you don’t

want a 4-wire-measurement) the two red plugs should be

connected and the two black plugs as well. Use short circuit

plugs or laboratory cables for this purpose. Without this

connection a measurement of voltage is not possible!

Caution: keep a sufficient distance to power leading parts of the

cables between solar generator and measuring device. These

cables may lead high tension what may affect your health even

without direct contact!
