5.1 Adjusting the V Amp Overshoot
Always perform the overshoot adjustment described below whenever a V amp has been replaced.
Preparations
(1) Have on hand an oscilloscope that can be set to output square waves at a ±2 V output level and a 1-Hz
frequency.
(2) Prior to measurement, mutually connect the GND terminals of the oscillator and the WR1000.
(3) Perform adjustment using a precision screwdriver with a plastic handle. (A precision screwdriver with a
metallic handle cannot be used because it causes noise to mix with the waveforms.)
(4) To perform adjustment, remove the plastic rivet covering the adjustment hole for each trimmer, as shown
in the photograph below.
