Opis: High Impedence Voltmeter Null Detector
Informacje:
                                    The Fluke Model 845 High Impedance Voltmeter-Null Detector
allows measurement of dc voltages from one microvolt to 1000
volts dc inl9 ranges. When used as a null detector on the
100 millivolt range and below, the input impedance is 10
megohms- A linear recorder output allows the instrument to
be used for production testing and also as a dc amplifier
with a maximum gain of 120 db.
1-3. The instrument consists of the line powered Model 845A,
and the line-battery-powered Model 845AB. The instruments
are half-rack in size, and are equipped with resilient feet
and a tilt-up bail for field or bench use. A single
instrument may be mounted in a standard 19 inch rack by
means of metal handle rack adapter kit 881A-102. Two
instruments may be mounted side-by-side in a standard 19
inch rack by means of metal handle rack adapter kit 881A-1Q3.
1-4. ELECTRICAL SPECIFICATIONS
