applied pressure.
2. Available “Measurement Mode” functions:
A. Zero Adjustment: Press MODE / # keys together 3 seconds. This initiates
automatic zero adjustment; ADJ briefly appears on LED display and then returns to Measurement Mode.
B. Peak / Bottom (Min. Max.) Hold Display: Displayed as $ or # keys are held
for more than 3 seconds and display shows PE+. Values are reset when power is restored to the unit, or: Reset Peak: Hold $ key, then press # key Reset Bottom: Hold # key, then press $ key
C. Key Lock: Prevents overwriting values / tampering – can not be reset by restor-
ing power. Lock:Press MODE and $ keys together;Lo( appears on LED display for 1 second. Unlock: Press MODE and $ keys together; UnL appears on LED display for 1 second.
3. Function Setting Mode: Used for product settings, except comparator-switch set­ting. Accessed by pressing MODE key for more than 3 seconds (complete menu attached).
A. Comparator Selection: Select ‘Hysteresis’ (kYS) or ‘Window Comparator’ (Yn).
Hysteresis: Switch remains activated until reset point has been achieved. Window Comparator: Switch activates each time pressure enters a set ‘pres­sure band’ determined by the A and B settings.
B. Comparator Operation Selection: Select nPn or PnP. Note: LED ring is Blue
with nPn and Green with PnP.
C. Filter Dampening Setting: This is based upon a moving average of pressure
data to reduce display “bounce” and smooth analog output due to system pres­sure fluctuations. User configurable with five selections: 25ms, 250ms, 2.5s, 5s and 10s. Filter will not be applied if 0 is selected.
D. Power-Save (Energy-Saving) Setting: Product is equipped with automatic
LED display turn-off feature. User may elect to turn-on display when reading pressure or using as an indicating instrument.
E. LED Ring Feature Setting: Turns Red when comparator-switch is ON and Blue
(nPn) or Green (PnP) when comparator-switch is OFF.
F. Display Unit Setting: User may alter unit of measures from standard to arbitrary. G. Display Settings: Allows for decimal point adjustment. H. Analog Output Scaling: Available with only 1 comparator; function sets analog
output for pressures corresponding to Zero (4mA) and Span (20mA) adjustment in percentage figures. Analog output under zero point pressure: After A-L is displayed, select the per­centage corresponding with the current analog output value under Zero (4mA) using # or $ keys – when pressure range displayed is set to 0.0-100.0% FS. Analog output under span point pressure: After A-K is displayed, select the per­centage corresponding with the current analog output value under Span (20mA) using # or $ keys – when pressure range displayed is set to 0.0-100.0% FS.

than 3 seconds. A. Comparator-Switch Setting: To activate / deactivate comparator-switch,
scroll to US1 (4-20mA version only) or US2 and select USE / noU. Enter com­parator-switch set point by selecting A-1 or A-2 and use #/$ keys for pres­sure setting. Now enter ‘deadband’ value (pressure difference between set and reset values) by selecting b-1 or b-2 and use #/$ keys for setting. Note: unit automatically configures the reset point. Increasing setpoint is entered as a positive ‘deadband’ value, while decreasing setpoint is entered as a negative ‘deadband’ value.
B. Loop Check: Allows the user to check comparator-switch operation without
requiring pressure input. Use $ or # keys to view comparator-switch function in a simulated test of the application.
