Relative Measurements 

Zero Reference shows the present measurement result 
with respect to the defined value. Use this feature to 
monitor the measured value in relation to a known good 
value. 

To setup: 

1. Push 

 to open the Scope and Meter button bar. 

2. Push 

1

 to open the MEASURE A button bar. 

3. Push 

2

 to enable the relative measurement 

(Zero On). 

4. Push 

4

 to close the MEASURE A menu and 

button bar. 

The relative measurement is now the main reading, 
and the former main measurement is now the smaller 
secondary reading position. 

5.  Repeat Step 1 to Step 4 to disable the relative 

measurement.
