Calibrating and Testing the Device
Calibrating with Insta Cal
Insta Cal's calibration feature calibrates the offset and gain corrections for the miniLAB
1008's analog inputs. These corrections are stored in nvRAM. You should calibrate the
miniLAB 1008 every six months.
You can calibrate an individual channel, a range of channels, or all channels at the same
time. If you calibrate only selected analog input channels, any existing calibration
coefficients for channels not included in the calibration are preserved.
The pin numbers and associated signals on the miniLAB 1008 are specified below for
differential mode. Refer to these pin numbers when making connections to the inputs
