qualified technicians who have access to the following:

Equipment: The class of calibration should be 10 times greater than the 
measured meter.

Step 1: Short the J3 with jumper.

Step 2: Apply 65 mV to the T1 input from Volts Calibrator and wait till the 
reading becomes stable, then press the SET key until the display shows 0.1.

Step 3: Apply Type K 0°C to the input T2 and wait till the reading 
becomes stable, then press the SET key until the meter shuts off by itself.

Step 4: Remove the jumper from J3.
