Room temperature calibration
1. Turn off the TAP-CLAMP.
2. Place the TAP-CLAMP at constant temperature at 25 ± 3 °C con-
dition for 2 hrs. to ensure the temperature of the K – thermocou-
ple to be even.
3. While holding [UNIT], press [ON / OFF] until display shows
"CALL"
4. Release both buttons, the display shows "00"
5. Press [UNIT] button < 1 sec. to adjust the number to "09"
6. Press [ON / OFF] button < 1 sec. to show a code of temperature.
7. Wait the temperature code reading to be steady, press [ON /
OFF] button < 1 sec.
8. The display shows the ambient temperature.
9. Press [ON / OFF] button < 1 sec. to quit the temperature calibra-
tion.
