1. Determine the maximum over voltage installation
category (CAT I ~ CAT IV) the clamp-on will be used
in and narrow your choice to those meters meeting
the requirement. The Category rating for each meter
is listed in the specifications table on page 3.
2. Narrow your choice by selecting meters with the
features required for your intended applications. For
example, if your applications require a CAT III meter
with frequency and capacitance measurement
capability, the TPI 265 ,TPI 270, or TPI 275 would
be good choices.
3. Finally, select a meter with enough range,
accuracy, and features for the tests you will perform.
For example, if you have narrowed your choice to
the TPI 265, 270, and 275 and your applications
require the capability to capture motor inrush
amperage, the analog peak hold of the 270 and 275
make them the better choice.
