Notes ※1. Internal input resistance of volt-ohm meter should be higher than 10k-ohms.
テスターは、入力抵抗10kΩ以上のものをお使い下さい。
※2. Adjustments should be made in case of the PC Board or Transistors being changed.
調整はPC ボードあるいはトランジスタを交換した場合に行って下さい。
※3. After feeding 1～10 watts output for about 15 minutes, check bias adjustment again.

Setup in adjustment mode : A power supply is turned on with Meter switch in OFF position, and it will become
adjustment mode if Hold Time switch is pushed on 8 times or more within a time which an output muting relay turns on.
Connect the Standard Dummy Load of 8Ω/100W or more, and also Digital Volt-meter to A-60 output as shown
below. Adjust the input signal so that meter reads exact 20.0V
If a METER switch is made into a "BAR" position (Fig.3) and a HOLD TIME switch is pushed 5 seconds or more
(Fig4), it will become the check of "50W" display and the calibration will be started.
In several seconds, a display shows "50W" and returns to the display of a soft setting date(Fig3) after this.
