1V range
VR101
RANGE: 1V
1) Input 1kHz (or 400 Hz), 1 Vrms sine wave, and set the pointer to 10.0 V of the 0-
10 scale. Check that the variable range is less than 98% and more than 102%
with respect to 10.0 (full-scale).
2) Waveforms shown on the oscilloscope shall not be deformed.

characteristics
1) Input 1kHz (or 400 Hz), 1 Vrms sine wave, and adjust the oscillator output so that
the pointer of the set points at 9.0.
2) Adjust the TC so that the pointer points at 9.0 when the frequency is changed to
100 kHz while the oscillator output remains unchanged.

point
Hi change-over point (102%): VR201
Lo change-over point (27%): VR202
1) Hi adjustment
Input 1 kHz, 1.02 V sine wave, and make adjustment so that the range will
change at the 102% point.
2) Lo adjustment
Input 1 kHz, 0.27 V sine wave, and make adjustment so that the range will
change at the 27% point.
3) Check that the Hi-Lo change-over operation is normal.
