Overview

1.1 Overview and Features

The PD3259 is a phase detector equipped with a voltmeter,
enabling it to be used to measure line voltages, check phase order,
measure frequency, and check for live wires and the ground phase
in 3-phase circuits.
By letting users check the state of 3-phase circuits at a glance, the
instrument delivers a high level of safety. In addition, because it lets
users measure line voltages, verify that wires are live, and check
phase voltages and the ground phase at once, it eliminates wiring
errors and reduces work times.
3-phase line voltage measurement
The instrument measures line voltages in
a 3-phase circuit from outside the wires'
insulation (without any metal contact).
Frequency measurement
Missing-phase prediction function
Phase detection function
The instrument detects normal
and reversed phase order for
3-phase circuits.
Hold function
The instrument holds the display
screen in the same state.
