Self-Test And Permanent Memory Storage U) - Keithley 595 Instruction Manual

IEEE-488
PROGRAMMING
4.9.25 Self-Test and Permanent Memory Storage (J)
Purpose
The J command is used by the Model 595 to perform tests on its memory elements
and to permanently store ca.K%ration constants
Format Jn
Parameters
n = 0 Perform G&test
n = 19 Store calibration constants in permanent memory
Description
Self-test--When the JO command is sent over the bus, the instrument performs the
following tests on its memory elements:
1. ROM test
2. RAM test
If the self-test is successful, the self-test error bit in the Ul status word will be set
to 0. Otherwise this bit will be set to 1. The test does not affect any data within the
memory.
Permanent Storage-When the Jl9 command is sent, calibration constants are stored
in permanent memory if the calibration jumper is configured to "store".
Reference
The instrument performs a number of self-tests on power-up. Calibration and subse-
quent storage of calibration constants are explained in Section 7.
Enter the following statements into the computer to perform the self-test:
When the END LINE key is pressed the second time, the instrument performs the
self-test. If successful, the self-test error bit in the Ul status word will be set to 0.
