FUNCTION DEFINITIONS (cont)
Alarm Set Point High 2 (SPH2)
SPH2 is independent and functions identically to SPH1. SPH2 has its own open collector outputs and front panel LED (H2).
Alarm Set Point Low 2 (SPL2)
SPL2 is independent and functions identically to SPL1. SPL2 has its own open collector outputs and front panel LED (L2).
Alarm Hysteresis High (HH)
HHis the hysteresis value for the alarms SPH1 and SPH2. The hysteresis value determines the number of counts the displayed reading must fall below SPH1 and SPH2 values before deactivating their respective open collector outputs and LEDs. The maximum value of hysteresis is 99 counts while the minimum is 00 counts.
Alarm Hysteresis Low (HL)
HL is the hysteresis value for the alarms SPL1 and SPL2. The hysteresis value determines the number of counts the displayed reading must exceed the SPL1 and SPL2 values before deactivating their respective open collector outputs and LEDs. The maximum value of hysteresis is 99 counts while the minimum is 00 counts.
FS Cal (CAL)
This input allows the user to calibrate the full scale readout to any desired engineering units. This input must be entered prior to performing the calibration. The FS Cal number may be any number from 1 to 99,999. Zero is an invalid FS Cal number. For best resolution and stability, choose a CAL number between 2000 and 19000 counts.
Example: If the Flowmeter is to be calibrated at a full scale flowrate of
500 sccm, the FS Cal value could be 500.00, 500.0 or 500. If the FS Cal value of 500.00 is used, the unit will automatically count by 3 when full scale calibration is completed since the
