a. Refer to "Specification".
4.10 Procedures: TC (mV) Input/Output
1. Connect the instrument to the calibration equipment:
• TC (mV) input = Figure 9b
• TC (mV) output = Figure 9d
2. Let the equipment get to a stable temperature
(minimum: 5 minutes since the last power on).
3. Use the calibration menu (Table 9) to do the
calibration:
• TC (mV) input = three-point calibration (-FS, Zero
and +FS).
• TC (mV) output = two-point calibration (Zero and
+FS).
The display shows the applicable instructions to
complete the calibration.
4. To make sure that the calibration is correct, select the
applicable TC (mV) input or output task (Table 2) and
apply the necessary values:
• TC (mV) input: -10, 0 (short circuit)
• Then TC (mV): 25, 50, 75
• TC (mV) output: -10, 0, 25, 50, 75
5. Make sure that the error is in the specified limits
(Table 20).

75 0.001 0 0.000 99
4.11 Procedures: IDOS UMM
Refer to the user manual for the IDOS UMM.
When the calibration is complete, the instrument
automatically sets a new calibration date in the UMM.
5. Specification
All accuracy statements include one year stability.
