6. Press to return to the previous screen.
7. Press to select Calibrate Full-Scale.
8. Use until the meter reads the value shown in the Set
Output To line, then press to save the value.
Use the following procedures to calibrate the analog inputs after replacing
the optional I/O expansion board. These procedures include selecting
analog input channels, calibrating them to zero volts, and then calibrating
them to full-scale using a known voltage source.
Use the following procedure to calibrate the input channels to zero volts.
1. From the Main Menu, choose Service > Analog Input Cal.
The Analog Input Cal screen appears.
Note If Service Mode is not displayed, refer to “Accessing the Service
Mode” on page 7-4, then return to the beginning of this step. ▲
2. At the Analog Input Cal screen, press to scroll to a channel, and
press .
3. With the cursor at Calibrate Zero, press .
The screen displays the input voltage for the selected channel.
4. Make sure that nothing is connected to the channel input pins and
press to calibrate the input voltage on the selected channel to
zero volts.
The screen displays 0.00 V as the voltage setting.
5. Press > to return to the Analog Input Cal screen and
repeat Steps 2 through 4 to calibrate other input channels to zero as
necessary.
6. Continue with the “Calibrating the Input Channels to Full-Scale”
procedure that follows.
