Model 410C

1-1. DESCRIPTION.

1-2. The Hewlett-Packard Model 4l0C Electronic Voltmeter can be used to measure DC voltage and DC current; AC voltage and resistance. Positive and negative DC voltages from 10 millivolts to 1500 volts and positive and negative DC currents from 1.5 microamperes to 150 milliamperes can be measured full scale. Resistance from 10 ohms to 10 megohms full scale can be measured with an accuracy of ±5% of reading at midscale; resistance from

0.2ohms to 500 megohms can be measured with reduced accuracy. The Model 410C Electronic Voltmeter is shown in Figure 1-1;the specifications are given in Table 1-1.

1-3. With the Model 11036A detachable AC Probe, the Voltmeter can be used to measure AC voltage from 20 cps to 700 Mc. From

20 cps to 100 MC) AC voltage from 0.5 to 300 volts can be measured; from 100 Mc to 700 Mc, refer to Figure 3-5 for maximum AC voltage that can be applied to the AC Probe. For additional information on the AC Probe, refer to Paragraph 1-8.
