REF at
Calibration
To compensate for fluorescence light source
degradation, the lamp light intensity value is
captured during calibration and is subsequently
used to compensate the fluorescence signal.
This captured reference value may be viewed in
the Calibrate menu. NOTE: altering the “REF at
Cal” value will alter the unit calibration, and
should only be done under Arjay authorization.
Zero
Oil PPM value for zero scale mA output (4 mA).
0.0ppm
Span
Oil PPM value for full-scale mA output. (20 mA)
100.0ppm
mA Action
Direct (20mA when PPM is at Span) or Inverse
(4mA when PPM is at Span.
DIR
Relay1 Hi Set
Alarm Relay 1 High Setpoint: Alarm condition if
PPM is above this value.
10 PPM
Relay1 Lo Set
Alarm Relay 1 Low Setpoint: Alarm condition
cleared if PPM is below this value.
10 PPM
Relay2 Hi Set
Alarm Relay 2 High Setpoint: Alarm condition if
PPM is above this value.
20 PPM
Relay2 Lo Set
Alarm Relay 2 Low Setpoint: Alarm condition
cleared if PPM is below this value.
20 PPM
Alarm Delay
Amount of time in seconds the PPM value must
be above the Hi Setpoint for the Alarm condition
to activate. (Maximum 99 seconds)
0 sec
Alarm Enable
“ON: – Enable Alarm Relay
“OFF” - Prevents relays from reflecting the
Alarm condition.
ON
Filter
Moving Window Filter tracks the average of the
last N samples. Higher values provide more
stable readings (Max. 1000)
960
Gain
Adjustable gain on the unamplified FLR
SIGNAL. Should only be modified if directed by
an Arjay Representative
same as
fixed gain
