stops and output is de-energized when the device operates (used
in
conjunction
with the
TIMER STOP MODES
of
N.O. and N.C).
6.
TIME UNITS Selection- Selects the mode
of
count; either cycles
or
seconds.
7.
OUTPUT Mode - The following two selections are available
PULSE - When selected, the output
of
the test set is on for a short, specified time
period (default is 5 cycles) and then
is
turned off. (Should the device under test
operate after pushing the START Button, the output will be de-energized). This
position is
normally used when setting the test current prior to the timing test and
providing short high current pulses for instantaneous tests. However, the duration
of
this output pulse can be programmed via the Display Menu. (See the Section III,
E.
Front Panel Display and Programming Menus.) (Default Setting).
MAl NT. - When selected, and the START Button is pressed, the control circuit
maintains the output
of
the test set until the device under test operates or the STOP
Button is pressed. This is the normal position for Time Delay tests.
VOLTS (voltmeter selection) Switches
8.
VOLTS - three different selections are available for display
IN
- When this voltage display selection is made, the voltage at the input plugs
of
the
test set will be displayed (Default Setting).
OUT - When this voltage display selection is made, the voltage at the output
terminals
of
the test set will be displayed.
EXT. - When this voltage display selection is made, the voltage applied to the EXT.
VOLTS terminals will be displayed.
9.
EXT. VOLTS terminals - These two terminals enable the digital voltmeter to
measure external a.c. voltages up to
600 Volts.
AMMETER
10. AMMETER RANGE Switches - Selects the desired full scale range
of
the meter.
NOTE: The output current level from the test set must be at least 8 percent
of
any full scale value before the ammeter will indicate an output reading. Please be
aware that changing ammeter ranges while the output is energized may
result
in erroneous ammeter readings. The 4 range selections are
0.2kA1
2kA1
20kA I
and 200 kA range. Default Setting is the 200 kA range.
11.AMMETER MODE
MEM/CONT - Selects the mode
of
the ammeter circuit. In the MEM position, the
highest measured current is indicated on the ammeter.
The
CONT mode permits
