IMPORTANT!
SSi strongly recommends that anyone who performs these calibrations have previous experience
with and strong working knowledge of this type of procedure. If in doubt, contact SSi at 513-772-
0060 to request assistance or to have the unit returned to the factory for calibration. An
improperly performed calibration will significantly impact temperature readings in a negative
way.
To perform a millivolt calibration (Zero and Span):
Needed: Copper wire (not thermocouple wire), millivolt sourcing device
1. Open the Analog Input Calibration page.
2. Make sure that the selected input at the top of the screen is mV.
3. Prepare the millivolt sourcing device. This device should be capable of sourcing a specified raw
voltage between 0 and 1 volt.
4. Connect the copper wire from the millivolt device to the white input jack labeled “CU”
(uncompensated) on the side of the case.
5. Tap Zero on the touch screen.
6. Configure the millivolt sourcing device to deliver zero millivolts.
7. Wait for the “Current Value” displayed on the screen to get as close to zero as possible.
8. Tap Calibrate. Tap “Yes” when asked if you want to proceed with the calibration. A progress
indicator will appear.
9. When the process completes, Zero calibration is finished.
10. Tap Span on the touch screen.
11. Configure the millivolt sourcing device to deliver the desired voltage at the high end of the
desired span.
