High Voltage Test Time
This procedure sets the length of time the HT-PR
will conduct the high voltage test. The test
time is specified by the safety agencies and is tied to the test voltage. Most safety agencies will
allow a much shorter test (usually 1 second vs 1 minute) if the voltage is increased by 20%. The
HT-PR is factory set for 2 seconds. Consult the safety agencies for the test time for the type of
equipment being tested. If a different test time is required, use this procedure to set it.
1.
Connect the HT-PR to a correctly rated source of supply and turn the power switch to the
I or ON position. Push the
RESET
button. The yellow
TEST
indicator should light,
indicating that the HT-PR
is ready to test.
2.
On the rear panel turn the
Test Time
potentiometer (see figure 4). As soon as the
potentiometer starts turning, the meter will display “d” (See figure 10) and the value can
be set in 1 second increments from 1 to 60 seconds.
3.
If tamperproof settings are desired, the
Test time Limit
control shaft may be pulled
away with a slight tug. (It may be reinserted for future adjustments).

Leakage Current Level
1.
AC Leakage Current can be set from 1.0 to 20.0 mA. DC Leakage Current can be set
from 1.0 to 5.0 mA. To set the leakage limit follow the steps below.
2.
Connect the HT-PR to a correctly rated source of supply and turn the power switch to the
I or ON position. Push the
RESET
button. The yellow
TEST
indicator should light,
indicating that the HT-PR is ready to test.
3.
For the HT-3000 use the AC/DC button to select the type of output voltage.
4.
On the rear panel turn the
Leakage Limit
potentiometer (see figure 4). As soon as the
potentiometer starts turning, the meter will start blinking, display “L” (See figure 11),
and the value can be set in 0.1 mA increments from 1.0 to 20.0 mA AC or 1.0 to 5.0 mA
DC.
5.
If tamperproof settings are desired, the
Leakage Limit
control shaft may be pulled away
with a slight tug. (It may be reinserted for future adjustments).
