Procedures (CH1): TC mV (measure or source)

Do the procedure as follows:
1. Connect the applicable calibration equipment (Ref: Table
8-1)
2. Let the equipment get to a stable temperature
(minimum: 5 minutes `since the last power on)
3. Use the calibration menu (Ref: Section 8.1) to do a three-
point calibration
(-10 mV, Zero and 100 mV) for the measure or source
function
4. Check the calibration is correct:
• Select the applicable TC mV (measure) or (source)
function (ref Section 2.12)
• Apply the necessary values
• TC mV (measure): -10, 0 (short circuit)
• TC (mV): 10, 25, 50, 100
• TC mV (source): -10, 0, 10, 25, 50, 100
5. Check the error is within limits (Ref: Table 8-14)
