A. Clamp:

 Measure inductive AC current. Opens to 1.25” (31.7mm).

B.  Conductor Alignment Marks:

 Used to aid the visual alignment of a conductor

  when measuring inductive amperage. Greatest accuracy is achieved when the  

  conductor inside the clamp is centered at the intersection of these marks.

C.  Wire Separation Tab/NCV sensor:

 Used to isolate an individual wire from a 

  bundle for testing. NCV sensor detects live voltage.

D.  Test Lead Holder:

 Used for hand-free use of the test probes.

E. Worklight: 

Lights clamp area in dark work environments.

F.  Category Max Indicator:

 Maximum CAT Rating for Clamp/jaw.

G.  Hand Guide:

 Used as a point of reference for the operator’s safety.

H.  NCV Alert Light:

 Indicates voltage when in NCV mode.

I.  Clamp Lever:

 Opens and closes current clamp jaw. The clamp uses a high- 

  tension spring to close the jaw. Do not allow fingers or objects to become  

  pinched in the base as the jaws close.

J.  Hold Button

 

  • Press to hold the reading on the display. Press again to return to live reading.
  • Press and hold to turn on Worklight and Backlight. Press and hold again to  

    turn off.

K.  Function Dial:

 Turns on meter and is used to select the function.

L.  Select Button

  • Used to choose measurement mode from a single dial selection; AC or DC  

    volts, Resistance, Continuity, Diode or Capacitance, ˚F or ˚C in temperature mode.
  • Press and hold the button while turning the meter on to disable Apo    

    (auto power off).

M. Max/Min Button

  • Press to enter MAX/MIN mode.
  • Press repeatedly to alternate between Maximum and Minimum readings.
  • Press and hold to return to live readings.

N.  Range Button:

 

  • Press repeatedly to cycle through manual ranges.
  • Press and hold to return to auto ranging mode.
 •

 

AT is displayed on LCD only during auto ranging mode.

O. Apo:

 Auto power off after 30 minutes of use. Press and hold the SELECT button  

  while turning the meter on to disable Apo (auto power off).

P. Display:

 

  • High contrast display.

Q. Category Max Indicator:

 Maximum CAT Rating for input jacks.

R. Input Jacks:

 Multifunction and Common jacks.

 •

 

Multifunction input port used for measuring: AC or DC volts, Resistance,  

    Continuity, Diode, Capacitacne, DC µA and temperature.
 •

 

Use CAT III test leads or higher.

S. Serial Number
T. Magnetic Mount:

 For hands-free work.

U. Battery Cover:

 Easy access for replacing batteries.

V. Battery Cover Latches:

 Convenient, quick opening.

W. Test lead holders:

 For storing test leads when not in use.

Test Lead Notes

Cat IV and CAT III Measurement Locations

•  Ensure the test lead shield is pressed firmly in place. Failure to use the CAT 

IV shield increases arc-flash risk.

CAT II Measurement Locations

•  CAT IV shields may be removed for CAT II locations. This will allow testing 

on recessed conductors such as standard wall outlets. Take care not to lose 

the shields.

 WARNING:

 Test Lead category protections apply only to test leads and 

should not be confused with the meter’s specific CAT rating. Observe the 

maximum category protection indicated on the meter the test leads are 

plugged into.

 CAUTION

:  If the test leads need to be replaced, you must use a new one 

which should meet EN 61010-031 standard, rated CATIII 1000V or better.

  When the batteries are too low for safe 

operation, the Low Battery indicator will display.

•  Rotate latches until Unlock symbols are aligned 

with arrows. Remove battery cover.

•  Replace the old batteries with 2 new (AAA) 

batteries.

•  Replace the battery cover.
•  Rotate latches until the lock symbols are aligned 

with arrows.
