Instrument Operation
Alarm
mAmp
Set up to 3 alarms: high, low, and an error signaling contact.
• Relays 1 and 2 (RLY1, RLY2) are normally open dry contacts used to set
high and low alarms for measurement values
• RLY 1 options: Off, Hi, Low
• RLY 2 options: Off, Hi, Low
• Relay 3 (RLY3) is a normally closed contact that can be dedicated to
errors. This will close if power to monitor is lost. This alarm is effected
by calibration, errors and offline or hold status
• RLY 3 options: Off, Cal, Hold, Err
• Default: All alarms (1, 2, & 3) are set to off
Set either of 2 analog current outputs (Sout & Tout), set scale values as
linear or logarithmic curves for concentration.
Analog outputs:
• Toggle between 4-20 mA or 0-20 mA current signals.
• The outputs share a common return, but are isolated from the main
circuitry of the monitor.
• Default output current: 4-20 mA
• Sout: dedicated ammonia output.
• Tout: dedicated temperature output.
• Toggle between logarithmic (LOG) and linear (LIn) scale for each.
• Set Low (LO) and high (HI) limits for Sout and Tout.
• Default scale values: for both Log and Lin.
Default Concentration:
• Low limit: 1.0 ppb
• High limit: 100 ppb
Default Temperature:
• Low limit: 5.0 degrees C
• High limit: 45.0 degrees C
mADJ
Set the mAmp offset adjustment value.
• Select the Sout or Tout output.
• Toggle the numeric offset value and positive or negative offset value.
• Default: 00.00 mAmp.
