11.2.2 Calibrate Analog

Select the Analog Output you wish to calibrate. Each Analog output can be calibrated at 4 and

20 mA.

Connect an accurate milliamp meter to the Analog output terminals and then adjust the ﬁve

digit number in the display until the milliamp meter reads 4.00 mA and repeat for 20.00 mA.

As the ﬁve digit number is increased the output current increases and as the number is

decreased the output current decreases. Thus coarse changes in the output current can be

made by changing the thousands or hundreds digits and ﬁne changes can be made by

changing the tens or ones digits.

Pressing the [ENTER] key after entering both values will bring up a conﬁrmation screen.

Selecting No will discard the entered values, selecting Yes will make the entered values the

current ones.

11.2.3 Calibrate Unlock

Select this Menu to conﬁgure the CAL Menu, see Section 7.

Selecting Yes means that Meter and Analog Output calibration Menus will be selectable under

the CAL Menu. Selecting No means that only the Sensor calibration is available under the CAL

Menu. Press [ENTER] after the selection to display a conﬁrmation screen.
