7 Calibrations

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.

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 start 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:

24/33
