Pressure Calibration (PCAL)
You can do a field pressure calibration using this function.
After PCAL is displayed, use the [SELECT] key to enter the
submenu. LO-P will be displayed for one second, and then
the switch’s interpretation of the actual pressure will be
displayed. Apply 0.0 psig to the unit. Use the [UP/DOWN
ARROW] keys to adjust the pressure display to zero psig.
Press the [STORE] key. The display will show HI-P for one
second, followed by the switch’s interpretation of the actual
pressure applied. Apply Full- Scale pressure to the unit. Use
the [UP/DOWN ARROW] keys to set the display equal to
Full- Scale pressure. Press the [STORE] key to return to the
main menu.
A pressure source is required for this operation. In addition,
calibration equipment used must have an accuracy of at least
± 0.02% F.S.O. of the switch being calibrated.
If re-calibration results in zero or Full-Scale readings that have
shifted by 4% F.S.O. or more from the factory calibration, an
error code of EROR will be displayed.
Reset (rSET)
This command resets the Smart-Switch TM to factory default
settings. After rSET appears, press [SELECT], [STORE],
[RUN] and [SELECT] to reset the unit to factory defaults.
These are as follows:
r-Hi returns to factory F.S.O.
r-Lo is set to zero
Spli is set to 60% of the full range.
SPld is set to 40% of the full range.
SP2i is set to 70% of the full range.
SP2d is set to 30% of the full range.
Switch delay is set to 0 mSec.
Display update time is set to 0.5 seconds.
