8842A

Instruction Manual

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.

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.
