Kategoria: Przyrządy pomiarowe
Grupa: Kalibrator
Opis: DC Voltage Calibrators
Informacje:
                                    1-2. The Fluke Model 341Ä and Model 343A' DC Voltage
Calibrators provide dc voltages of 0 to 1100 volts in three
ranges. Voltages are selected by eleven-position decade
switches, which provide in-line, digital readout of the
instrument output voltage. The Model 341A employs six-dial
readout» with 1 ppm resolution, and the Model 343A employs
seven-dial readout, with 0.1 ppm resolution.
1-3. A controlled current limiter, a fixed current limiter,
and an electronic crowbar circuit provide protection against
instrument malfunction and operator error. Output current or
voltage, depending on function desired, are continuously
monitored by a front panel meter.
1-4. The instruments are designed for rack-mount
installation, using the mounting brackets supplied, and are
equipped with resilient feet and tilt-down bail for field or
bench use.
