Appendix B: Operator Performance Checks
This appendix contains performance checks for many of the functions of the
1502C. They are recommended for incoming inspections to verify that the
instrument is functioning properly. Procedures to verify the actual performance
requirements are provided in the 1502C Service Manual.
Performing these checks will assure you that your instrument is in good working
condition. These checks should be performed upon receipt of a new instrument
or one that has been serviced or repaired. It does not test all portions of the
instrument to Calibration specifications.
The purpose of these checks is not to familiarize a new operator with the
instrument. If you are not experienced with the instrument, you should read the
Operating Instructions chapter of this manual before going on with these checks.
If the instrument fails any of these checks, it should be serviced. Many failure
modes affect only some of the instrument functions.

correct for the voltage you are using (115 VAC requires a different fuse than
230 VAC).
Pull the POWER switch on the front panel. If a message does not appear on the
display within a second or two, turn the instrument off. There are some failure
modes that could permanently damage or ruin the LCD if the power is left on for
more than a minute or so. Refer to Appendix C: Operator Troubleshooting in this
manual.
