A R
PE
voltage polarity indication, indicates the polarity of the DC voltage at the 4 mm test
sockets K and L. For AC voltage, “+” and “–“ are displayed alternately.
B Current clamp measurement enabled
C
Ω
NULL
R
PE
null offset, is displayed in case of a compensation (null balance) of the measuring
lead resistance
D Attention, hot surface! If the symbol is displayed, immediately disconnect the
BENNING PV 1-1 from the PV generator. Connect the BENNING PV 1-1 only after the
symbol has disappeared.
E Polarity indication, indicates the polarity of the DC voltage at the PV test sockets
9
and
J
F
c
Attention, dangerous voltage has been detected
G R
PE
LOCK, enabled, if a continuous R
PE
measurement has been activated
H
m
Attention, if this symbol is activated, observe the instructions contained in the operating
manual in order to avoid danger.
I R
ISO
(pass)/ (fail), indicates whether the measured insulating resistance is within the
preset limiting values
J Selection of the insulation test voltage, displays the testing voltage of the insulating re-
sistance measurement
K Error, see specific error codes for further details (More details in chapter 9.1. “Error codes”)
L STORE, LCD data are stored in the internal memory
M RECALL, stored LCD data are loaded from the internal memory
N Storage location indicator, indicates the current storage location (1…200)
O Voltage / current deviation, indicates a deviation of the measured open-circuit voltage and
short-circuit current values of more or less than 5 %
P Battery symbol, is displayed to indicate discharged batteries
5. General information
The BENNING PV 1-1 is intended for electrical safety tests according to VDE 0126-23 (DIN EN
62446).
The BENNING PV 1-1 automatically tests connected PV modules or PV strings. All measuring
results are displayed on the large LC display.
- At full battery capacity, the BENNING PV 1-1 allows to carry out up to 3000 automatic mea-
surements of Vo/c, Is/c and R
ISO
(500 V).
- Appliance dimensions:
(L x W x H) = 270 x 115 x 55 mm
- Appliance weight: 2600 g
6. Environment conditions:
- The BENNING PV 1-1 is intended for making measurements in dry environment.
- Maximum barometric elevation for making measurements: 2000 m,
- Over voltage category/ Siting category: IEC/ EN 61010-1 → 1000 V category I (this apply to
the red
9
and black
J
PV test socket),
- Over voltage category/ Siting category: IEC/ EN 61010-1 → 300 V category III (this apply to
the red L and black K 4 mm test socket),
- Contamination class: 2,
- Protection Class: IP 50 (DIN VDE 0470-1 IEC/ EN 60529)
IP 50 means: Dustproof, (5 - first index). No protection against water, (0 - second index).
- EMC: IEC/ EN 61326,
- Operating temperature and relative humidity:
For operating temperature from 0 °C to 30 °C: relative humidity less than 80 %
For operating temperatures from 31 °C to 40 °C: relative humidity less than 75 %
- Storage temperature: The BENNING PV 1-1 can be stored at any temperature in the range
from - 25 °C to + 65 °C (relative humidity from 0 to 90 %). The battery should be taken out of
the instrument for storage.
7. Electrical specifications
Note: The measuring precision is specied as the sum of
- a relative fraction of the measured value and
- a number of digits (counting steps of the least signicant digit).
This specied measuring precision is valid for temperatures in the range from 18 °C to 30 °C and
relative humidity less than 80 %.
