External Current Sensor Input
(/EX1, /EX2, /EX3)
Current can be measured by
using current clamps without disconnecting power supply wiring
(voltage output type). By setting an external current sensor
conversion ratio, it can support various types of current
clamp-on probes. |

VGA Output (/V1)
By connecting to a monitor,
you can create large displays of numerical values and waveforms.
This function is convenient for simultaneously confirming data
on multiple monitors, or to check data remotely. |

Harmonic Measurement (/G5)
This function enables
simultaneous measurement of normal and harmonic data. Harmonic
components of up to the 50th order can be measured. With the
WT500 you can simultaneously confirm voltage, current, and the
distortion factor (THD) as well as measure the distortion factor
without switching modes. |

Delta
Computation (/DT)
This function allows you to
calculate individual phase voltages and phase currents from the
line voltages and phase currents measured in a three-phase,
three-wire (3P3W) system. The phase voltage can be calculated
from the line voltage measured with the three-phase, three-wire
(3V3A) method. This is useful when you want to determine the
phase voltage in a DUT with no neutral line by using the
three-phase, three-wire (3V3A) method.
Note:
This function cannot be installed on products with only one
element. |

Added Frequency Measurement (/FQ)
In addition to the standard
two channels of frequency measurement, an option is available
for frequency measurement on all channels. This option provides
frequency measurement of voltage and current on all channels
with input elements 1 through 3 installed. This is necessary
when you want to measure voltage and current frequency from the
instrument's I/O as well as voltage and current frequencies of
multiple items under test at the same time.
Note:
This function cannot be installed on products with only one
element. |
