Information

The model 165 Autoranging Multimeter is a highly versatile 3-1/2 digit instrument capable of handling almost every measurement that will ever be encountered in most lab or production line facilities. The 165 measures 10 microvolts to 1000 volts dc, 10 microvolts to 500 volts rms ac, 10 milliohms to 200 megohms, 1 nanoampere to 2 amperes dc, and 0.1 microampere to 2 amperes rms ac. The specified ac frequency response of the ac volts and amps ranges is 20 Hz to 20kHz. Usable reading may be obtained typically from 10 Hz to 100-kHz. Thirty of the thirty-two ranges of the 165 are capable of 100% over ranging, the two exceptions being the highest voltage ranges. This allows the user to accurately exceed a full-scale reading without having to immediately change range. The AUTO range mode of the 165 allows ranges to be changed automatically when an input signal exceeds 2000 counts or falls below 0179 counts on the display. A 1mA Current source is built-in. FEATURES. a. Direct-Reading Display. The polarity decimal point, and engineering units of a reading are automatically shown on the bright, easy-to-read display panel. b. Automatic or Manual Range Selection. The 165 provides for automatic or manual selection of all thirty-two ranges by rotating the RANGE switch (inner knob) to the appropriate setting. c. Thirty-two Ranges. The 165 provides six ranges of dc voltage, six ranges of ac voltage, eight ranges of resistance (Including the extra range provided by the 1mA current source), seven ranges of dc current, and five ranges of ac current. d. Analog Outputs. The model 165 has two nominal 1-volt analog outputs for monitoring purposes. e. Built-in 1mA Current source at up to 4 volts.
