11.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.
11.1 Calibration Apparatus
● A voltage and current generator (Yokogawa 7651 or the
equivalent)
● A voltmeter (Yokogawa 7562 or the equivalent)
● A precision resistor of 250 ⍀ ± 0.01%, 1 W (for current output)

11.2 Calibration Procedure
Connect the instruments as shown in Fig. 10.1. First adjust the output-1 signal and then the output-2 signal.
Produce input signals equivalent to 0, 25, 50, 75, and 100% of the
input span (or those equivalent to 0, 6.25, 25, 56.25, and 100% of
the input span if square root extraction is set) from the voltage and
current generator to the distributor. Then, check that the
distributor’s output signal shows voltages corresponding to 0, 25,
50, 75, and 100% of the input span within the rated accuracy range.
