assess the need for more advanced equipment such as power quality analyzers
•
  Verify system performance and quickly troubleshoot problems during 
installation projects to minimize downtime
•
 Convenient, everyday tool for those working on critical machinery
•
  Maintaining large, complex HVAC systems in factories, data centers, hospitals 
and commercial buildings
•
  Best tool for techs who need the following critical measurements during  
HVAC system checks and repairs: 
  – Capacitance for checking startup capacitors 
  – Micro Amps for the verification of the flame sensors 
  – Temperature for checking cooling/heating performance 
  – Inrush current for verification of the compressor motor 
  – Low-pass filter to allow measurement of the variable frequency drives

TOUGH ON 
 ANATOMY OF 
THE JOB.
EASY ON THE WALLET.
With so many key features, Amprobe’s new Navigator Clamp Meters serve as a first line of 
defense in any industrial setting. Spot check and verify system conditions before deploying 
more specialized tools — or incurring additional costs. 
What’s more, the Amprobe Navigator Clamp series boasts some of the most robust 
features, including:
•
 Phase sequence
•
 Power and power factor measurements
•
 Total harmonics distortion
•
 Individual harmonics
•
 Low-pass filter
NAVIGATE EASILY THROUGH ANY JOB
Designed for one-hand operation, our innovative navigation system eliminates  
push buttons. Instead, all Navigator Clamps incorporate an easy-to-use joystick  
that allows the users to select functions directly on the large backlit display.

TYPICAL NAVIGATOR™ CLAMP APPLICATIONS
Motor Testing. Use inrush current to test motors, capacitance to check startup 
capacitors, and phase rotation to measure three-phase systems.
Power Quality. Quickly verify the efficiency of the electrical system by 
measuring power factor and working power measurements. Check for  
harmful harmonics while you perform daily system checks.
Transformers. The Navigator Clamp is the ideal tool for maintenance 
and installation.
Facility Maintenance. Perform routine load studies, motor testing, power 
quality measurements and HVAC system checks. 
HVAC Maintenance. Use many of the key functions on the ACD-51NAV 
including capacitance, micro amps, temperature, inrush current and low-pass  
filter for routine HVAC maintenance.
