ITEM MEASUREMENT & ADJUSTMENT REMARKS
Adjustment of level meter
Battery indicator
2. Connect a new battery or power supply line to the input.
3. Connect a memory scope, counter or oscilloscope to the specified
portion of the printed circuit. board. |
4. Emit the signal from the transmitter 3 times a second. Then, adjust
semi-fixed resistor VR1071 so that the indication of the counter is
within the specification.
5. Criterion.
The output time of the counter should be 98 ~ 103 msec.
Precautions
1. The signal from the transmitter should be emitted at least 3 times a
second.
2. The temperature during measurement should be 20+8°C. |
3. The inhibition time of the first signal should not exceed 115 msec.
4. \n the case of a unit of low impedance, the measurement and input
adjustment should be carefully made because the value of resistance |
of the time constant is larger than MQ (10°).
5. The ist, 2nd and 3rd signals from the transmitter vary in inhibition
time. Therefore, suitable intervals should be observed for signal emis-
sion.

2. Adjust the power supply voltage so that the en voltmeter indicates
10V.
3. Turn on the power switch and the receiver,
4. Adjust the semi-fixed volume of R1028 so that the level meter indi-
cates the position shown at fig. 14. _
5. Criterion.
When the power supply voltage is 10.0+0.3V, the meter’s pointer:
should be within the range of 1~2 as shown at fig. 15.
Precautions
1. The meter should be observed from in front.
2. Care should be taken not to apply over current to the ctor
3. The meter should be used without removing it from the set.
