Preliminary Test Procedure
The following procedure should be followed before start-
ing functional tests.
1.
Position the test set controls as follows:
a. TRIP BREAKER-PROGRAMMER ONLY Swilch as
desired.
b. PROGRAMMER TYPE Switch-Position per pro-
grammer type (A or B).
c. PROGRAMMER CURRENT SETTING-Must match
the programmer current satting.
Functional Tests
d. TEST SELECTOR-Long Time/Short Time.
e. TEST CURRENT ADJUST -Completely counter-
clockwise.
2. Record the "IN SERVICE" settings of the programmer
so that these set poinls can be restored upon completion of
testing. See page 22.
3. Connect the test set power cord to the 105-125-Vac
power source.
4. Turn power switch "ON".
NOTE: In using the test set, it is never necessary to calculate test current values. If the test
set and programmer controls are set
as
described for each of the functional tests on the
following pages, the TEST CURRENT value will correspond to programmer face plate
values. (e.g. the meter will read 1.50 for
a
SHORT TIME PICKUP of
1.5C
or for an
INSTANTANEOUS PICKUP of 1.5X etc.)
LONG TIME PICKUP Test
Purpose
Verify that pickup occurs within tolerance. Each program-
mer is equipped with a convenient LED LONG TIME PICKUP
light permitting a straight forward visual means of determin-
ing when the LONG TIME PICKUP point is reached.
Test Procedure
1. Programmer Settings:
LONG TIME PICKUP (if present)-1.1C
2. Position Test Set Controls:
PROGRAMMER CURRENT SETTING-Must match the
programmer's CURRENT SETTING
TEST SELECTOR-Long Time
3. TEST CURRENT -Preset a TEST CURRENT of 0.95
4. Push START

'These values applicable only to programmers with the adjustable LONG
TIME PICKUP option
5. Slowly increase the TEST CURRENT, carefully observ-
ing the LONG TIME PICKUP light on the programmer. The
light will indicate when the pickup point is reached.
6. Read the TEST CURRENT value at which pickup oc-
curs and compare with the acceptable limits of Table 1 (1.1 C
setting).
7. If'the programmer is equipped with an adjustable
LONG TIME PICKUP, repeat the above test at 0.8C, O.9C and
1.0C.
