Point Calibration from Menu screen
The Two Point method of calibration is the most accurate way
to calibrate the transmitter with two level points. The current
level must be known and should be held steady for accurate
calibration. They may be any two points at more than 10% apart,
and need not be the 4mA or 20 mA points.
The Point Calibration pop-up window is accessed by clicking on
the menu "button" Point Calibration. Either a high point or a
low point can be entered first.
A. Type in the current level value as the high point of the
two point calibration.
B. Click on Hi Point or press Enter (or Tab) on the
keyboard. High point calibration is now complete.
C. Lower level in vessel a minimum of 10%.
D. Type in that the current level for Low Point of the two
point calibration.
E. Click on Low Point or press Enter (or Tab) on keyboard.
Low point calibration is now complete.
Level calibration uses zero and span capacitance values as
the calibration data . These values can be obtained from the
AMETEK Drexelbrook Service department (or from a previous
calibration or identical application). Please be prepared when
you call (1-800-527-6297) with the purchase order number and
the serial number of the transmitter.
A. Go to Level Calibration area of the menu.
B. Enter Lower Level value. Press Tab or Enter.
C. Enter Lower Capacitance value. Press Tab or Enter.
D. Enter Upper Level value. Press Tab or Enter.
E. Enter Upper Capacitance value. Press Tab or Enter.
F. Click on Write to Transmitter.
