This instrument can execute Voltage TRMS measure, automatic detection of AC/DC voltage, Frequency, Resistance and Test Continuity.
An innovative feature of H191 model it is the execution of tests with ONE HAND only, without use, typical of multimeters, of any other test lead except the integrated test lead. In this way are possible simple and fast Voltage and Frequency measures with only contact of integrated lest on cable.
This feature execute and enhance the function of common "phase detection meter". Other new (patented) features of HT191 instrument are the phase rotation detection and the phase coincidence measure (fundamentally important on correctly connection of two different three phase systems).
In these cases the meter can perform test with integrated test lead only, directly with contact also on insulation part of cables.
HT191 meter is the optimum for any installer, industrial switchboards constructors and for each operator who find an instrument to execute safety and fast measures.
