7 Calibration
AM8010 is designed for temperature measurement by measuring
the probe resistance and converting it into a temperature.
Consequently, the resistance measurement is very critical, and the
instrument must be calibrated correctly. Every AM8010 is
calibrated before shipment.
AM8010 needs regular calibration performed by qualified
professionals. One year calibration interval is recommended.
Users can calibrate AM8010 using standard resistors with
calibrated values. Users can choose to do one of the two
calibrations：Instrument Calibration and System Calibration.
7.1 Instrument Calibration
Instrument Calibration is to calibrate the resistance measurement
accuracy of AM8010.
Note: a standard resistor with resistance of 100 ohm is required for
the Instrument Calibration.
Set AM8010 to Calibration Mode before starting the calibration
(See Chapter 4.1). Calibration steps are as followings:
1. Connect a 100 ohm standard resistor with four-wire
configuration to AM8010. In the illustrations below a
standard resistor with 100.0038 ohm resistance is used as an
example. It is suggested to use external power adapter or to
connect the AM8010 to a USB interface on a running
computer during calibration. If battery power is used make
sure the batteries are not running low.
Power on AM8010, and the LCD should display:
