Operation Manual

HOLD function
The maximum voltage value can be „stored“ on the
display when activated the button „HOLD“. The value
is recorded for approx. 30 seconds or until you press
button „HOLD“ again. The Hold-function is stopped
when again a voltage is impressed.
Note: When the measured value does not vary for
2 sec, then the maximum value is recorded.
4.3 Resistance measurements (Ω)
Before taking any resistance measurements always
check that the test object is at zero-potential.
Connect 4 mm standard test lines to the Ω- and
-socket. Adjust the device to Ω. Ohm is indicated in
the upper display line.
Note:
The arrow signalizes „out of measurement range“.
The measurement range serves for a denite
determination of impedances of 0,1 Ω – 20 MΩ.
A selection between Ω-, kΩ- and MΩ ranges occurs
automatically after applying to the impedance.
The green LED signalises resistance values that a
lower than 10 kΩ.
4.4 Current measurement (I)
Attention!
You may perform current measurement in Ex-areas
only in measuring circuits with peak values of
maximum 50 V.
You may only measure currents up to maximum 2 A.
Connect 4 mm standard test lines to the A- and
-socket.
The measurement range serves for measuring
AC/DC currents in the range of 1 mA – 2 A.
A selection between mA and A occurs automatically
after attaching the test prods.
Attention!
The moulded fuse activates with currents of more
than 2 A.
The fuse can only be changed by the manufacturer
(see section 7).
4.5 Current measurement with clamp-on ammeter
MZ 1005 (I ashes)
Attention!
Measurements with MZ 1005 are only permissible
in Ex I-areas.
Please observe the separate user instructions of the
clamp-on ammeter MZ 1005. Connect the MZ 1005
to the 7-pin universal connector.
Within the clamp-on ammeter range you can mea-
sure AC/DC currents between 0,1 and 1000 A, the
optimal measurement range is selected automati-
cally.
