Data Hold 

The 

HOLD

 function freezes the reading on the display for later 

viewing. 

Manual and Automatic Ranging 

The MultiPro™ series multimeters are Autoranging, with manual 
override. 

Smart Power Auto Power Off 

Smart Power shuts the meter down automatically after approximately 
17 minutes of inactivity.  

Audible Beeper 

To disable the audible meter tones, press and hold the Hz key while 
powering the meter. 

Automatic Test Lead Resistance Compensation 

Automatically compensates for the resistance of the test leads, as well 
as the internal protection circuitry automatically, ensuring greater 
accuracy of low resistance measurements. 

MAX/MIN mode (MP530 only) 

MAX/MIN mode stores the minimum and maximum readings in 
memory for later viewing.

 

 Relative mode (MP530 only) 

Relative mode allows the meter to display the difference between the 
actual measurement and a stored reference value.  

Zoom mode analog pointer (MP530 only) 

The Zoom mode magnifies the regular analog bar graph resolution (up 
to 5 times) to show small signal changes  

Peak

C

 capture mode (MP530 only) 

PeakC captures voltage or current signal that have durations as short 
as 5ms. This mode is available in DCV, ACV, DCA, & ACA functions.
