MODE
touch-screen key to select measurement mode (LINEAR or NONLINEAR). Currently
selected mode is displayed on the bottom of the key.

CON
(connection) touch-screen key to select measurement connection (INT or PLUG). Currently
selected connection is displayed on the bottom of the key.

LIMIT t
touch-screen key to select limit time (1 s or 5 s), valid for internal measurement only.
Currently selected limit value is displayed on the bottom of the key.

voltage may be alternating or direct there is an
appropriate information AC or DC added to the unit.
10 ... Measurement result status (symbol
in green colour - result OK, symbol
in red colour - result
not OK).
5.8.4. TRIGGER CONDITIONS
The instrument recognizes disconnection of mains voltage on TRIG input (INT measurement) or on
U
RES
input (PLUG measurement) when one of the following two conditions occurs:
If mean value of rectified input voltage drops down with a slope of at least 25 V / s (mean value
measured each period), then trigger is activated and the measurement starts to run.
This condition will occur for example if AC or DC input voltage starts to decrease.
Momentary value of current half period is compared with momentary value of previous half period
(the same polarity). If there is a difference higher than 10%, then trigger is activated and the
measurement starts to run.
This condition will occur for example if AC voltage changes to DC.
The above two conditions are active on U
RES
input in PLUG mode and on U
TRIG
input in INT mode.
