AUTORANGING/MANUAL RANGE SELECTION 

When the meter is first turned on, it automatically goes into Autoranging. This automatically 
selects the best range for the measurements being made and is generally the best mode 
for most measurements. For measurement situations requiring that a range be manually 
selected, perform the following: 
1. Press 

the

 RANGE

 button. The “

Auto”

 display indicator will turn off. 

2. Press 

the 

RANGE

 key to step through the available ranges. Observe the decimal 

point and units displayed until the preferred range is located. 

3. 

To exit the Manual Ranging mode and return to Autoranging, press and hold the

 

RANGE

 key for 2 seconds. 

Note:

 Manual ranging does not apply for the Capacitance and Frequency functions. 

RELATIVE MODE 

The relative measurement feature allows you to make measurements relative to a stored 
zero reference value. A reference voltage, current, etc. can be stored and measurements 
made in comparison to that value. The displayed value is the difference between the 
reference value and the measured value. 
1. 

Perform the measurement as described in the operating instructions. 

2. Press 

the 

REL

 button to store (zero) the reading in the display. The "

REL

" indicator 

will appear on the display. 

3. 

The display will now indicate the difference between the stored value and the 
measured value. 

4. Press 

the 

REL

 button to exit the relative mode. 

Note:

 The Relative function does not operate in the Frequency function. 

HOLD 

The hold function freezes the reading in the display. Press the 

HOLD

 key momentarily to 

activate or to exit the 

HOLD

 function. 

AUTO POWER OFF 

The auto off feature will turn the meter off after 30 minutes.  

LOW BATTERY INDICATION 

The 

 icon will appear in the display when the battery voltage becomes low. Replace the 

battery when this appears.
