Press scroll key and the display will show
. Change the
ohm's value to 300 ohms .Press scroll key for at least 3 seconds.
The display will blink a moment and two values are obtained for SR1
and REF1 (last step). Otherwise, if the display didn't blink or if any
value obtained for SR1 and REF1 is equal to -199.9 or 199.9 ,
then the calibration fails.
