Measurement
Using the zero-adjust feature makes more reliable measure-
ments possible by adjusting the resistance-range and voltage-
range zero values of the instrument. Using the zero-adjust fea-
ture is recommended prior to measurement. The zero-adjust
feature sets the current measurement value (adjusted value) at
0 and displays subsequent measurement results.
3.3 Zero-adjustment
To prevent short circuits, do not place the
zero-adjust board on top of the battery.
• The zero-adjust feature takes approximately four
seconds.
• Using the zero-adjust feature adjusts the zero
points of all ranges.
• Even after turning off the power to the instru-
ment, the adjusted values will remain and the
zero-adjust feature will not be cancelled.
• After replacing the test lead, be sure to use the
zero-adjust feature prior to measurement.
• Be sure to use the included zero-adjust board for
the zero-adjust feature.
• Be sure to keep the test lead shorted during use
of the zero-adjust feature. Keep the tip of the test
lead away from the metal components.
