③ Motor power (
P
m measurement)
Measurement type
Digital computation from the measured voltage or pulse signal.
In the case that the 9603 channel A unit is torque and channel B
unit is rotation count/rate.
Accuracy
± 1dgt. with respect to the value computed from the measurement
values
Display range
0.1 to 130% of setting voltage range when both channel A and B
is set to DC voltage measurement
0 to 100% of using frequency measurement range when channel B
is set to pulse measurement.
Unit indication
W
Calculation
The calculation is carried out as follows, depending on the torque
units set for channel A.

7. Frequency measurement ( fa, fb, fc)
(when using the 9600, 9601, 9602)
Measurement type
Reciprocal calculation from frequency of input waveform
Number of measurement
channel
3 channels
Display range
AUTO/ 50 Hz/ 500 Hz/ 5 kHz/ 50 kHz/ 2 MHz
Resolution
99999 counts
Measurement range
500.00 mHz to 50.000 Hz/ 20.000 Hz to 500.00 Hz/
200.00 Hz to 5.0000 kHz/ 2.0000 kHz to 50.000 kHz/
20.000 kHz to 2.0000 MHz
Measurement accuracy
±
0.1% rdg.
±
1dgt.
With a sine wave input from 10% to 130% of the U / I ranges,
when the frequency characteristics of the input unit forming the
source are within the specified range
Function
Switching U / I source
(Simultaneous U / I input from a single input unit is not possible.)
Filter switching linked to range (high-pass or low-pass filter)
Pulse measurement when 9603 is used
When the 9303 is set to pulse measurement, fc is forced to pulse
measurement of channel B.
