Record the room temperature immediately prior to zeroing.

Shorting Plug (white, mini-T/C connector with internal copper short) on the
M130’s connection and press ENTER key. Display will show BUSY.
When ZERO is successfully completed, the message “ZERO PASSED” is
briefly displayed and the M130 is automatically returned to the Measure
Mode. Remove the Shorting Plug. The new temperature reference for the
M130 will be the ambient temperature recorded prior to zeroing. (Note:
factory reference temperature is 23
°C.)
If the ZERO is unsuccessful, the message “ZERO FAILED” will be displayed
briefly. In this case, check to be sure the Shorting Plug is properly installed
and repeat the ZERO process. If “ZERO FAILED” appears again contact
