Kazragami The reading on the bridge is approximately 9. The modulated signal is transformer coupled to a demodulator driven at the same 3 kHz rate as the modulator. The Recorder Output Option Checks require the use of a dc differential voltmeter. DC Voltage Range Calibration To calibrate the Kelvin-Varley Divider, apply ac power to the instrument and proceed as follows: Transistor Q8 is driven in Synchronism with the chopper Ql and Is operated in the inverse mode to secure minimum saturation voltage. Tektronix D1 Curve Tracer.
