The Simpson D.C. Millivoltmeter Model 387 features ranges of 10, 30, 100, 300, and 1,000 millivolts with a full scale deflection current drain of 750 microamperes. The unit’s accuracy is 3% of full scale over an ambient temperature range of 50º to 120º Fahrenheit. At extreme temperatures from -55º to 185º Fahrenheit, an additional error of no more than 2% of full-scale deflection may be expected. Easy range selection is provided by the use of large binding posts on an engraved-filled panel.
For servicing gas-fired equipment, checks safety thermocouples.
