5. Operation

5.1 RANGE Button

The Autorange mode automatically selects the proper range for the measurement being 
made and is generally the best mode for most applications. For measurement situations 
requiring that a range be manually selected, perform the following:
• Momentarily press the RANGE button. The “AUTO” indicator will no longer be shown on 
   the LCD display.
• Momentarily press the RANGE button to step through the available ranges until the 
   desired range is selected.

True RMS Digital Multimeter/ English

13/12/2017 Version No. 001

The measurement category(CAT)rating and voltage rating is determined by a combination 
of the meter, test probes and any accessories connected to the meter and test probes. 
The combination rating is the LOWEST of any individual component.

WARNING: 

Operation is limited to CAT II applications when the insulated tips are 

removed from one or both test probes. Refer to Input Limits section in this manual for 

maximum voltage ratings.

3-3.Maintenance

This multimeter is designed to provide years of dependable service, if the following care 

instructions are performed:

• KEEP THE METER DRY. If it gets wet, wipe it off.

• USE AND STORE THE METER IN NORMAL TEMPERATURES. Temperature extremes can 

   shorten the life of the electronic parts and distort or melt plastic parts.

• HANDLE THE METER GENTLY AND CAREFULLY. Dropping it can damage the electronic 

   parts or the case.

• KEEP THE METER CLEAN. Wipe the case occasionally with a damp cloth.

   DO NOT use chemicals, cleaning solvents, or detergents.

• USE ONLY FRESH BATTERIES OF THE RECOMMENDED SIZE AND TYPE.

   Remove old or weak batteries so they do not leak and damage the unit.

• IF THE METER IS TO BE STORED FOR A LONG PERIOD OF TIME, the batteries should 

   be removed to prevent damage to the unit.
