Operating Overview

Setting A Measurement Reference

Setting A Measurement Reference

The reference set (Ref Set) function establishes a measurement reference point. This allows you to make a direct comparison between two measurement results, or between a measurement standard and the actual measurement results.

Depending on the type of measurement, referenced measurements are displayed in one of two ways:

1.Displayed value = Measurement − Reference. The difference between the measured value and the reference value is displayed.

or

2.Displayed value = Measurement ⎟ Reference. A ratio of the measured value to the reference value is displayed. This ratio is expressed in dB.

To set a reference

Step 1. Position the cursor in front of the unit-of-measure for the measurement you want to set the reference for.

Step 2. Press and release the Shift key, then the Incr ⎟ 10 key to access the Ref Set function.

Step 3. Enter a reference value, then press Enter. (To use the currently measured value as a reference, just press Enter.)

Step 4. The Reference indicator shows that an internal reference has been set.

Step 5. To turn the reference off press and release the Shift key, then the Incr ⎟ 10 key to access the Ref Set function, and then press the On/Off key.
