APPENDIX A: CALIBRATION

MANUAL RESET

A Manual Reset returns the OM-550 to a "known" condition. This is useful when troubleshooting or learning to program the unit.

AManual Reset programs the OM-550 as follows:

CH1 is a Voltage channel, m=1.00000, b=000000, dp=4, units = (63) "V".

CH2 is a Type K thermocouple Temperature channel.

CH3 through 5 are Skipped

CH6 is Skipped but defined as CH4+CH5, decimal fix=1, units = .00 (Blank)

The Temperature Units for all temperature channels are °C.

The Real-time Clock/Calendar is initialized to 00:00:00 01/01/00.

The Log Interval is 00:00:30 (30 seconds).

The OM-550 is in the Normal (not the Calibration) mode.

Tadjust = 00.0

The Rejection Frequency = 60Hz.

The data cache contains 100 "phony" points of data for channels 1 & 2.

The OM-550 is programmed to overwrite a full cache.

PERFORMING A MANUAL RESET

1.Turn the unit “OFF”

2.Press & hold the 5 key

3.Momentarily press the ON key

4.Release the 5 key

A collection of messages similar to the one shown in Figure A-1will be printed.
