SPECIFICATIONS
Input ( specify one)
120 V OR 240 V, 50/ 60 Hz, 1f, 20A
Output
Output Ranges: Continuously adjustable in three ranges to meet
a variety of test circuit impedances:
0 to 500 A at 3.5 V max.
0 to 125 A at 14 V max.
0 to 25 A at 70 V max.
Operating Modes ( switch-selected)
Memory
Normal
Digital Display
31/
2 digit, extra-bright LED display with 0.3-in. ( 7.62 mm) numerals
Ranges ( switch-selected)
0 to 19.99/ 199.9/ 1999 A/ 3.00 kA
Continuous Accuracy ( overall ammeter system)
± 1% of reading, ± 1 digit on three high ranges, ± 1 digit on low
range ± 1% of range
Timer
A solid-state digital timer is incorporated to measure the elapsed
time of the test in either seconds or cycles.
It uses a crystal-controlled oscillator, therefore, its accuracy is
independent of the line frequency.
Display: 5-digit, extra-bright LED display with 0.3 in. ( 7.62 mm)
numerals
Ranges ( switch-selected)
0 to 99.999 s
0 to 999.99 s
0 to 99999 cycles
Accuracy
± 0.005% of reading, ± 1 digit
Timer Control Circuit
This circuit automatically starts the timer when the output is
energized and automatically stops the timer and de-energizes the
output when the device under test operates.
This circuit accommodates the following test conditions by simple
switch selection of the appropriate mode:
Current Actuated: Used to test a device that has no auxiliary
contacts to monitor, such as a single-pole circuit breaker. The
timer stops when the output current is interrupted.
Normally Closed: Used to test a device with normally closed
contacts. The timer stops and the output is de-energized when the
contacts open.
Normally Open: Used to test a device with normally open
contacts. The timer stops and the output is de-energized when the
contacts close.
