Checking the Diode Test Function
To check the diode test function, do the following:
1 n the meter. . Connect the calibrator to the V and COM inputs o
2. Turn the rotary switch to

To verify the accuracy of the Temperature function, perform the Following:
teps 1 - 7 to the VTemp and COM inputs using a
