4 Assembly description
4.1 Measuring channels (1)
•
Each channel can measure the voltage U and the cur-
rent I.
•
Each channel is isolated against every other channel
and against the control unit in accordance with CAT III.
•
The measuring resistors in the circuit are designed as
specified on the imprint of the screen.
•
The polarity of voltage U and current I is arranged such
that the power P is positive (consumption) if the power
flows from left to right.
•
When voltage measurement of an AC voltage is activat-
ed, its frequency f can also be measured.
•
When the voltage and current measurement is activated,
the power P and for alternating values (RMS value), the
load angle φ and the frequency f can also be measured.
•
For alternating values (RMS value), if more than one
channel has been activated, the shift angle can be mea-
sured with respect to the reference value of channel A.
4.2 Mask (2)
•
Each channel is protected by a 16 A gR, which can be
replaced by removing the mask.
•
It can only be replaced after all test leads have been re-
moved and the device has been switched off (see safety
note).
•
The fuses can be pried out by using a screwdriver in the
slot on the side.
•
The device must not be operated with an open mask.
4.3 Display (3)
Display for manual measurement.

4.4 Rotary selector and OK button (4)
Turn the rotary selector
•
the menu bar (move left – right),
•
the settings menus (move up – down),
•
the range menus (move up – down),
•
value lists (move up – down).
In some settings menus, it is necessary to move to the right.
This can only be done with the cursor buttons (e.g., trigger
menu).
•
Only the rotary selector can activate a selection by
pressing OK. A setting is saved or opened in a sub-
menu.
