PEAK Peak
The Peak feature stores the highest pressure reading the instrument has measured since
the last reset or power up. At power up PEAK is reset to the present pressure reading. To manually
reset the PEAK value, press the RST (RESET) key while in PEAK.
VALY Valley
The Valley feature stores the lowest pressure reading the instrument has measured since
the last reset or power up. At power up VALY is reset to the present pressure reading. To manually
reset the VALY value, press the RST (RESET) key while in VALY.
DAMP Dampening
Adjust from 1-15. Dampening stabilizes the display from instabilities due to things such as vibration
and excessive pressure fluctuations. The dampening setting adjusts the amount of readings that are
averaged for each display update. Adjust the dampening value until the display reads a stable value for
the application.
AdU Advanced Menu
POL, Process Output Low, and POH, Process Output High are used to scale the transmitter output for a unit with
the output option of 4 to 20 mA, 0-5 VDC, 0-10 VDC, 1-5 VDC, or 1-6 VDC. Below shows with 4 to 20 mA output
option.
POL Process Output Low
Set to the desired display reading for the 4 mA output. May be set from 2% below
minimum scale up to POH.
POH Process Output High
Set to the desired display reading for the 20 mA output. May be set from POL to 2% above maximum
scale.
CAL – ZERO Zero Calibration
DO NOT apply any pressure when performing this function. With the display
reading CAL - ZERO, press the E key. The upper display will blink. Press the E
key again to complete the zeroing of the instrument or press the MENU key to cancel.
CAL – FS Full-scale Calibration
With the display reading CAL - FS, apply full-scale pressure to the unit, press the E key.
The upper display will blink. Press the E key again to complete the
calibration or press the MENU key to cancel.
trAn sets the transmitter output option function for a unit with the output option of 4 to 20 mA, 0-5 VDC, 0-10 VDC,
1-5 VDC, or 1-6 VDC. Below shows with 4 to 20 mA output option.
trAn
DIR Direct Output. 4 mA output at zero, 20 mA output at full scale pressure.
REV Reverse Output. 20 mA output at zero, 4 mA output at full scale pressure.
CAL - DFLT Factory Default Calibration
With the display reading CAL - DFLT, press the E key. The upper display will blink.
Press E again to restore the original factory calibration values or press the MENU key
to cancel.
