8842A
Instruction Manual
Note that a command may be valid in some parts of the calibration procedure but not in
others. The Get Input Prompt (G2) command, for instance, is not valid when the 8842A is
taking verification readings. The Rate (Sn) commands, for instance, are valid when the
8842A is taking verification readings, but they are not valid at any other time during
calibration. Table 6-15 shows when commands are invalid.
6-22
1. In remote calibration, you can store a 16-character message in the calibration
memory which can be read by the system controller. Possible uses include
storing the calibration date, instrument ID, etc.
2. Although some buttons are ignored in local calibration (e.g., the AUTO button),
the corresponding remote commands (e.g., R0) load the output buffer with an
error message.
3. The calibration memory is erased differently. (This is explained later.)
4. The rear panel SAMPLE COMPLETE signal acts slightly differently. During
calibration, the SAMPLE COMPLETE signal is inactive. When the 8842A is
taking verification readings, the SAMPLE COMPLETE signal acts the same as
in normal operation.
