connect the common (COM) test lead before connect-
ing the live lead ; when removing the test leads removing the
test live lead before removing the common test lead
.
The figures on the following pages show how to make basic
measurements.
Measuring AC/DC Voltage And Frequency
The non-zero display reading is normal when the meter test
leads are open, which will not affect actural measurement
accuracy. The meter will show zero or close to reading when
the test leads are shorted. In reading AC voltage or current,
reading-settling time increases to several seconds at the low
end of AC voltage and current ranges in rms models.
