5.3.2 Current Output (Optional)
To configure the M450 for 4-20mA current output, perform the following steps:
1. Set the analog voltage range to the 5 Volt scale as described in Section 5.3.1
above.
2. Install Jumper in J2 on the rear panel PCB assembly.
3. Set Jumpers JP3 and JP4 on the rear panel PCB assembly as shown in Figure
4.2 below.

5.4 A/D - D/A Calibration Procedure
Due to the stability of modern electronics, this procedure should not have to be
performed more than once a year or whenever a major sub-assembly is exchanged or
whenever analog output voltage range is changed .
To calibrate the ADC, do the following:
1. Press SETUP-DIAG.
2. Enter Diagnostic password and press NEXT until D/A CALIBRATION
appears in the display and press ENTR.
3. Press ADC to perform the A/D Cal.
