NOTE
• Measure for more than 60 seconds.
• If using a YOKOGAWA CA150, set the mode to “Frequency (FREQ) and Pulse” and the
range to “CPM”.
• An appropriate load (24 VDC ± 20%, 150 mA max) is required.
4) Measure the pulse output value in “pps” with a Yokogawa CA150 Handy Calibrator or
equivalent to simplify the measurement of pulses. If such a device is unavailable, use the
confi guration shown in Figure 6.3.13.
