V/Hz

Purpose .................... to show the measured Vpwm value
(see Vpwm) divided by the fundamental frequency
on Variable AC Motor Speed drives.
Accuracy ................................................... %Vrms + %Hz
AC motors are designed for use with a rotating
magnetic field of constant strength. This strength
depends on the applied vottage (Vpwm) divided
by the fundamental frequency of the appied
voltage (Hz). The nominal Volt and Hz value are
shown on the motor type plate.

Power (A and B, C and D)

Power Factor ........................ ratio between Watts and VA
Range ........................................................ 0.00 to 1.00
Watt ................................... RMS reading of multiplication
corresponding samples of input A or C (volts)
Full Scale Reading ....................................... 999 counts
VA ................................................................ Vrms x Arms
Full Scale Reading ....................................... 999 counts
VA Reactive (VAR) .......................................
Full Scale Reading ....................................... 999 counts
Note
and Input B or D (amperes)
√ 2
((VA) -W

Phase (A and B, C and D)

Range ............................................. -180 to +180 degrees
Resolution .......................................................... 1 degree
Accuracy
0.1 Hz to 1 MHz ........................................... ±2 degrees
1 MHz to 10 MHz ......................................... ±3 degrees

Temperature (TEMP)

With Optional Temperature Probe (
Ranges (°C or °F) .................................. -40.0 to +100.0 °
Probe Sensitivity ............................. 1 mV/°C and 1 mV/°F
Accuracy ........................................... ±(1.5 % + 5 counts)
(add temperature probe accuracy for overall accuracy)

Decibel (dB)

dBV ................................................ dB relative to one volt
dBm .................... dB relative to one mW in 50 Ω or 600 Ω
dB on .......................................... VDC, VAC, or VAC+DC
2 Accuracy .......................... same as VDC, VAC, VAC+DC
