l
mA2
Set the mA2 analog current output:
• Scroll 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
analyzer
• Default output current: 4-20 mA
Select Sensor or Temperature for this output (SEnS and tEnP)
If Sense -
• Scroll between logarithmic (LOg) and linear (LIn) scale for SOUt
• Set the low and high limits for the sensor output (SOUt)
• Default – 1.0 ppb (low) and 100 ppb (high)
If Temp -
• Set the low and high limits for the temperature output (tOUt)
• Default – 5.0 °C (low) and 45.0 °C (high)
l
mADJ
Set the mA offset adjustment value for the mA1 and mA2 outputs:
• Select the OUT1 or OUT2 output
• Scroll the numeric offset value and positive or negative offset value
• Default mA offset – 00.0 mA
l
TEST
Test relays and analog output lines (DIAGNOSTICS will appear in the mode indicator):
• Method to activate/deactivate relays and outputs to be tested
• Verify the accuracy of the analog outputs when used with an external loop calibrator
• Provides the values and settings for the mA output and relays
• mA output
• 4-20
• The low and high values represented by mA1 and mA2
• Relay status
• Set RLY1, RLY2 and RLY3 status to OFF or On
l
CAL
Set calibration frequency in hours:
• High limit is 19999 hours
• Low limit is 00000 hours
• Default setting – 720 hours
l
DYN
Set values for customized Dynamic Two Point Calibration (DYN):
• Programmable for the analyzer flow rate; concentration (ppm), percent flow and range of
standard 1 and concentration (ppm), percent flow and range of standard 2
• Default analyzer flow rate: 40 mL/minute
• Default standard concentration: 2 ppm
• Default standard 1 (Std1) percent flow (Hydrazine): 99.9%
• Default standard 1 (Std1) range: x/100
• Default standard 2 (Std2) percent flow (Hydrazine): 52.5%
• Default standard 2 (Std2) range: x/10
