Pressing the [ENTER] key after entering Point 2 will bring up a confirmation screen. Select Yes
to save the calibration values and the successful Calibration is confirmed on the display. The
transmitter will return to the Measurement mode in approximately 5 seconds.
11.3.2 CalibrateAnalog
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 de-
creased 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 chang-
ing 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.
11.3.3 CalibrateUnlock

Selecting Yes means that Meter calibration menu (see chapter 11.3.1 ”Calibrate Meter”) and An-
alog Output calibration menu (see chapter 11.3.2 ”Calibrate Analog”) 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.
