Select the POSITIVE supply and any voltage within the
specified voltage range.
If the power module is in a high power compartment,
select any current from 50 mA to 0.750 A.
If the power module is in a standard compartment,
select any current from 50 mA to 400 mA.
CHECK-that the current meter reads within
+(5%
+
20 mA) of the selected current.
If the power supply is in the high power compartment,
select any voltage from 15 V or less. See previous
note.
Select any current from 1.6 A or less.
CHECK-that the current meter reads within
+
(5%
+
20 mA) of the current selected.
If the power module is in a standard compartment,
select any voltage from 15 V or less.
Select any current from 0.750 A or less.
CHECK-that the current meter reads within
+(5%
+20 mA) of the current selected.
Repeat steps a through
k
for the NEGATIVE supply.
Change the POSlTlVE to NEGATIVE. The voltages,
currents and tolerances remain the same. Only the sign
changes.
m. Leave these connections for the next step.

Check Constant Current Step Size
a. Turn the OUTPUT OFF.
b.
Connect the current meter to the front panel POSITIVE
and common terminals.

Performance Check Procedure
Select any voltage within the range of the instrument.
The selected voltage must be sufficient to force the
selected current through the internal resistance of the
current meter and associated leads.
Select any current within the specified range of the
instrument.
Turn the OUTPUT ON.
Note the current meter reading.
Change the current output up or down by 50
mA.
Note the new meter reading.
CHECK-that the second reading is from 35
mA to
65
mA from the reading obtained in step f.
Repeat the above steps for the NEGATIVE supply.
Leave these connections for the next step.
Check Constant Current Source Effect
Make certain the PS 5010 is in the high power
compartment.
Make certain the OUTPUT is OFF.
Connect a current meter from the front panel
POSITIVE connector to the common connector.
Set the PS 501 0 for 15 V output at 1.6 A.
Turn the OUTPUT ON. Allow the PS 5010 to stabilize
for 1 minute before proceeding.
Vary the line voltage to the power module from the
lower limit to the upper limit for the nominal line voltage
used.
