This calibration technique allows you

to independently trim the zero setting,

or enter an offset value without altering

the calibrated span range.

Choose (CH1) to display the LVDT 1 position, (CH2)

to display the LVDT 2 position, (CH 1+2) to display the sum

of LVDTs 1 and 2, or (CH 1-2) to display the difference

of LVDTs 1 and 2.

SP1 SP2 SP4SP3 SP5 SP6

This is a dual zero and span

calibration procedure.

Must bring sensor to NULL

position before calibrating.

This calibration technique allows you

to independently trim the span setting

without altering zero position.

Note, when trimming the span value,

the zero offset value is automatically

recalculated and adjusted for the new

scale factor.

Calibration Mode (Calibration of Sensor Position to Display)

The calibration mode is used to calibrate the physical position

of the sensor to the meter display. The calibration mode

provides four individual calibration techniques. These are:

• Adjusting the LVDT until the display reads zero.

• A dual position, zero and span calibration procedure.

• Independent trimming of the zero position or entry of an

offset value without altering the span.

• Independent trimming of the span position or entry of an

offset value without altering the zero.

Note:

Calibration procedures can not be carried out on a

signal (Result, CH1 or CH2) if the signal has an active

linearization table. The table or tables must be disabled

before calibration and then re-activated when calibration is

complete
