10.MAINTENANCE

The product starts running immediately when the power is turned on;
however, it needs 10 to 15 minutes of warm-up before it meets the
specified performance.
For cleaning the instrument, use a soft and dry cloth.

10.1 Calibration Apparatus

Pulse generator (Yokogawa FG100 or the equivalent): 1
A counter(Yokogawa TC100 or the equivalent) or oscilloscope
(Yokogawa DL1540 or the equivalent): 1
A precision resistor (1k

⍀, 1.6 k⍀): 1 each

6V battery: 1

10.2 Calibration Procedure

Connect the instruments as shown in Fig.10.1. First adjust the out-
put-1 signal and then the output-2 signal.
Produce a rectangular pulse of any frequency from the pulse genera-
tor to measure the value using a counter or oscilloscope. (Connect the
counter or oscilloscope as the broken line shown in figure 10.1.)
Next, connect the counter to the terminals 7 and 9, or terminals 2 and
5, then check that the frequency (input frequency x set rate) is output.
When using a oscilloscope, the wave shaping of output pulse can be
confirmed.
