TRANSMITTER CALIBRATION

In this function transmitter source and measure readings are both
scaled in engineering units for quick comparison. Transmitter may be
a linearized, non-linearized, 4-20 or 0-20 mA model for
thermocouples or RTD.

Setting-up a Calibration

Leave the cursor at NONE in the measure menu and select the
required source function. Go through the menu and make the
necessary selections. In the mode screen, select CAL to calibrate a
transmitter. Proceed to select all transmitter characteristics.

To Check or Calibrate a Transmitter

All normal key-pad functions are available to change the source. Use
the key to change to fixed steps. Use and keys to step
through 0%, 25%, 50%, 75% and 100% of the span as set-up. Press
to return to the normal key-pad functions. An ideal transmitter will
show equal readings. The difference of both readings is expressed in
% of the transmitter span or reading and is shown in the upper
window in small size digits.
