MEASUREMENT INPUT
Terminals (
13
):
Two sets of terminals are provided. The
V
, voltage terminals, is used to measure
external AC or DC voltages up to a maximum of 600 Volts. The
I
, current terminals, is
used to measure external AC or DC currents up to a maximum of 6 amperes.
Caution: Use properly rated CATII insulated test leads with the MEASUREMENT
INPUT and AC or DC AUX voltage output terminals, part number 684000 and
684001 (see accessory list).
AC AUX
Voltage Output Terminals (
14
):
These output terminals are used to provide AC voltage to the device under test. The
output is controlled by the
Control Knob
(
18
).
0 - 300 VAC MAX
: Up to 300 Volts AC is available from these terminals.
Warning: Lethal voltages present when outputs are on
DC AUX
Output Terminals (
15
):
These output terminals are used to provide DC voltage or DC current to the device
under test. The output is controlled by the
Control Knob
(
18
).
0 - 250 VDC MAX
: Up to 250 Volts DC is available from these terminals.
0 – 2.5 ADC MAX
: Up to 2.5 Amperes DC is available from these terminals.
Note: DC voltage is available from all Relay Test Screens. The selection of either
voltage or current is made from the
DC Relay Test Screen
.
AC
and
DC
Voltage Switches (
16
):
The
AC
or
DC
Voltage Switches control the
AC AUX
and
DC AUX
voltage outputs, on
and off. When either AC or DC voltage outputs are on, the lamp in the switch will be lit.
While in the ON position, the outputs stay on regardless of the state of the
INIT
Switch
(
24
). When testing Voltage Relays, the AC Voltage is dynamically changed from the
NORMAL to the FAULT Voltage when the INIT Switch is pressed. When the relay
operates the AC voltage output is turned off (see
Voltage Relay Test Procedure
).
