Operation Menu Parameters and Descriptions.
Alarm 1 High: This parameter represents the high process alarm or high deviation
alarm for Alarm 1. This parameter appears if your unit has an auxiliary output and
Ot3 = AL. See the model number. If AL 1 = Pr: Range: A1LO to rH Default: rH
AL 1 = dE: Range: 0 to -999°F/0 to -999°C/0 to -999 Units Default: -999°F
Alarm 2 Low: Represents the low process alarm or low deviation alarm for
Alarm 2. Appears if your unit has an auxiliary output and Ot4 = AL. See the model
number. If AL 2 = Pr: Range: rL to A2HI Default: rL
If AL 2 = dE: Range: 0 to -999°F/0 to -999°C/0 to -999 Units Default: -999°F.
Alarm 2 High: Represents the high process alarm or high deviation alarm for
Alarm 2. Appears if your unit has an auxiliary output and Ot4 = AL. See the model
number. If AL 2 = Pr: Range: A2LO to rH Default: rh
If AL 2 = dE: Range: 0 to -999°F/0 to -999°C/0 to -999 Units Default: -999°F
Calibration Offset: Adds or subtracts degrees from the input signal.
Range: -99°F to 99°F/-55°C to 55°C/-99 Units to 99 Units; or -99.9°F to
99.9°F/-55.5°C to 55.5°C Default: 0
Auto-Tune: This parameter initiates auto-tune for Output 1 in the heating mode
only. This parameter appears if Ot1 = ht. For more information on Tuning see
Chapter 6. Range: 0 = off, 1 = slow, 2 = medium, 3 = fast Default: 0
