5 220A
Instruction Manual
4-8
Caution
To ensure proper instrument operation make sure that both
screws are installed and that they are both in either the FRONT
or REAR locations.
1.
Disconnect the 5220A from line power.
2.
Remove both the top and large inner covers from the 5220A.
3.
Locate the output jumper screws as shown in Figure 4-1.
4.
Install and secure the screws in the two FRONT or REAR holes, as desired.
5.
Reinstall the top and inner covers.
4-19. Service
Tools
The 5220A comes equipped with an extender board for servicing other 5220A PCB
assemblies. A storage slot for the board is provided in the 5220A PCB assemblies. See
Figure 4-1 for the storage location.
4-20. Performance Test
The following paragraphs comprise a performance verification test that compares the
instrument’s performance to the specifications given in Section 1 of this manual. The test
is recommended as an acceptance test when the unit is first received, and later as a
calibration procedure to verify instrument accuracy at the scheduled calibration periods.
It is also useful as an aid in troubleshooting.
Test equipment required for the performance test is listed earlier in Table 4-1. If the
recommended equipment is not available, comparable instruments with equivalent
specifications may be substituted. To ensure optimum results, the test must be performed
at an ambient temperature of 22 to 24 degrees Celsius, with a relative humidity of less
than 85 %. Also the instrument should be allowed to warm up for at least 30 minutes
before starting the performance test.
If the instrument does not meet the performance test, troubleshooting, repair, and/or
calibration adjustment is indicated. Procedures for calibration adjustment and
troubleshooting are given later in this section of the manual.
4-21. Initial Conditions
Before starting the following procedures, condition the 5220A as follows:
1.
Disconnect all input, output, and remote connections at the 5220A.
2.
Install the top, bottom and inner covers if they have been removed.
3.
Connect the unit to line power through an autotransformer set for the proper line
voltage, and set the POWER switch to ON. Only the STANDBY and FRONT LEDs
should light.
4.
Allow the 5220A to warm up for at least 30 minutes before proceeding.
