or as a ratio). In addition, you can specify the nominal
current itself.
The available settings are listed below.
A-meter 1
Menu Settings Description

1)
Unit Ampere Current reading in Ampere
% of In Current reading as percentage
of nominal current
I1/I2 Current reading as the ratio of
generated current (I1) to current
measured by “AMMETER 2” (I2)
Nominal
Current Value in A Here you can set the value of
the nominal current
1) The value for range Low or High depends on the output
configuration, see "Specifications"
V/A METER
In this menu option you can select to use the voltme-
ter or the second ammeter ("A-METER 2"). You can
also modify the settings for the instruments. You can
select the range and the unit in which the reading is
to be expressed (volts/amperes or percentage of nomi-
nal voltage/current). In addition, you can specify the
nominal current/voltage itself and have the turns ratio
for a current transformer displayed.
First in the menu you have to select between "A-
METER 2" or "VOLTMETER". Select the desired
instrument by pressing
. The instrument will be
activated and you can now modify its settings.
The available settings are listed in the table below.

DC- Meas-
urement On/Off INGVAR can be set to measure
DC-current (A-meter 1 and 2) and
DC-voltage (V-meter). See note.
OFF Delay Cycles Specify the number of mains voltage
cycles which the automatic shut-off
is to be delayed (in accordance with
the preset stop condition).
