Measuring functions:
- protective earth conductor resistance measurement with test current of 200 mA
- open-circuit voltage measurement of the solar modules or PV strings up to 1,000 VDC
- short-circuit current measurement via an internal circuit up to 15 ADC without any danger for the user
- insulation resistance measurement between the active DC conductors (+/-) and earth with adjustable testing voltage of 250 V, 500 V, 1,000 VDC)
- functional test via current measurement up to 40 A AC / DC (by means of current clamp adapter BENNING CC 3, item no. 044038)
- the BENNING PV 1-1 is able to receive the measured values (insolation, PV module / ambient temperature and date / time stamp) of the insolation and temperature measuring instrument BENNING SUN 2 (optional, item no. 050420) via radio connection.

Features:
- clear and unambiguous display of all measurement results
- safe measurement connection, even if the photovoltaic system is delivering energy
- automatic testing procedure (open-circuit voltage 1000 V DC, short-circuit current 15 A DC, insulating resistance)
- automatic display of voltage polarity with audio/ visual warning for reverse polarity
- null balance of the measuring leads
- measured values memory for 200 display indicatons for (automatic) string-string comparison incl. warning in the event of short circuit current and open circuit voltage deviations > 5 %, download of measuring results occurs by means of USB interface
- the BENNING PV 1-1 is equipped with an integrated real-time clock which automatically adds a date / time stamp to each storage process or storage location
- Radio connection to the optional insolation and temperature measuring instrument BENNING SUN 2
- download software for the preparation of test certificates in MS Excel
- ISO measuring result with “pass / fail” information
- direct connection to all photovoltaic modules with MC4 or „Sunclix“ connectors
- easy operation for network-independently and mobile testing
- LC display with background lighting
- automatic switch off after 60 seconds
- the testing can be based on photovoltaic modules or the complete photovoltaic system
