• Notes
• The TF1041B is a Vacuum Tube Voltmeter. It measures a.c. voltages from 25 mV to 300 V, d.c. voltage from 10 mV to 1.000 V and resistance from 0,02 ohm to 500 Mohm; the frequency range for a.c. measurements extends from 20 Hz to 1.500 Hz. Seven ranges are used for a.c. measurements, eight for d.c.,and eight for resistance. On all d.c. ranges, a centre zero facility is available to aid precise determination of null point in bridges and discriminators.
