RCT 10, 11, 12, 13 Series

5.8 Point Calibration

Equipment Required:

• RCT Series HART

Smart Transmitter

• Model 275 HART

Calibrator

• 24V Power source

• Approximately 250 ohm total loop resistance

• Two known process levels applied to the probe

This procedure uses an example of a point calibration for

full-scale (20mA) = 35 ft. and zero (4mA) = 1.5 ft.

5.8.1 Fine Tuning Calibration

When a known level is available that is closer to an

endpoint than a previous calibration point, it may be used

as a new calibration point to increase accuracy. This is

done in the following steps:

ENTER THE UPPER CALIBRATION POINT and/ or

ENTER THE LOWER CALIBRATION POINT with the

new known level applied.

The order of execution between the upper and lower

calibration procedures does not matter. They can be done

at different times.

5.8.2 Selecting Engineering Units

The examples in this procedure use the default units of

feet. For other units, use the following procedure:

Connect the handheld communicator to the 4-20

mA loop per Figure 4-1.

Power the loop and proceed with following steps.

The procedure SET UP ZERO

AND FULL SCALE LIMITS

must be performed to set up the

vessel zero and full-scale limits

sometime prior to performing

a point calibration. This

informs the RCT Series of the

tank level limits and only

needs to be performed once for

a given installation.
