Measurement Ranges(1)

A measurement range determine the highest value the

Meter can measure. Most Meter functions have more

than one range. See "Accuracy Specifications".

A. Selecting a Measurement Range

Being in the right measurement range is important:

If the range is too low for the input, the Meter displays

to indicate an overload.

If the range is too high, the Meter will not display the

most accurate measurement.

B. Manual Ranging and Autoranging

The Meter has both manual range and autorange options:

In the autorange mode, the Meter selects the best

range for the input detected. This allows you to

switch test points without having to reset the range.

In the manual range mode, you select the range.

This allows you to override autorange and lock the

Meter in a specific range.

The Meter defaults to the autorange mode in measurement

functions that have more than one range. When the Meter

is in the autorange mode, is displayed.

To enter or exit the manual range mode:

1. Press RANGE.

The Meter enters the manual range mode and

turns off.

Each presses of RANGE increments the range.

When the highest range is reached, the Meter wraps

to the lowest range.

2. To exit the manual range mode, press and hold

RANGE for over 1 seconds.

The Meter returns to the autorange mode and

is displayed.

Note

In Hold, Max/Min mode, Press RANGE exits these

measurement modes and enters manual range mode.

In Hz measurement mode, Press RANGE to

attenuate 10 times of input signal amplitude which

can increase the Meter sensitivity and stabilize the

correct reading.

Press RANGE while turning on the power to enter

80,000 counts resolution except at capacitance

measurement.

Measurement Ranges(2)

When AC voltage measurement has been completed,

disconnect the connection between the testing leads

and the circuit under test, and remove the testing

leads away from the input terminals of the Meter.
