309 Гипатия Милли Омметр

309 — это миллиомметр от Гипатии. Когда инженерам необходимо собрать информацию об электрических соединениях, таких как провода, кабелепроводы или кабели, они используют миллиомметр. Эта часть электронного испытательного оборудования измеряет наименьшие значения сопротивления. Инженер будет использовать миллиомметр вместо традиционного омметра для документирования и регистрации величин сопротивления в нижней части шкалы (небольшие значения в омах).

Electrical

Impedance Measurement

Accuracy: ± 1% of reading (when the test current is &gt, 500μ / impedance in Ohms and &gt, 30 mA)
Range: 0 to 100 Ohms
Measurement Technique: Successive approximation analog to digital conversion of sensed voltage and current
Measurement window: Either 2 or 3 full sine waves depending upon line frequency (e.g. 3 at 60 Hz, 2 at 50 Hz)
Sample rate: ~ 53 KHz, yielding ~ 2.6K voltage and 2.6K current samples per measurement window at 60 Hz, and ~ 2.1K voltage and 2.1K current samples/window at 50 Hz
Mathematical conversion to true rms voltage and current values, division independent of phase to yield impedance
Display derived from four layer stack averaging
Voltage is sensed at the probe heads by internal probe sense lines or, for Model 109 probes, by precision Kelvin sensing

Digital Current Measurement

Accuracy: ± 1% of reading ± 4 mA
Range: 0 to 144 Amps rms

Bar Graph Current Measurement

Accuracy: ± 1% of reading ± 4 mA at transition points (every 2.5 Arms)
Range: 2.5 to 77.5 Amps rms (0 to 2.5 Arms implied) (Note 3, Graph 2)
Measurement Technique: Logical translation of digital current measurement

Digital Timer

Accuracy: ± .1% (Digital Timer and Audio / Visual Alerts applicable to Model 309 or, if server driven, Model 308)
Range: 1 second to 59 minutes, 59 seconds (extended times possible under server software)
Internal Reference: 16.777 MHz (2e24) crystal controlled system clock

Audio/Visual Alerts

When enabled, sounds and flashes when any user specified test current or impedance limit is violated
Accuracy: Logically detected. The accuracy therefore exactly matches the accuracy of associated measurements

Operating Duty Cycle

Continuous to test currents of 35 Amps
Derate linearly to 50% duty cycle at 60 Amps
Maximum Cycle Period: 35 to 60 Amps: 4 Minutes
Maximum allowed common mode voltage to ground: 50 Vrms, 71 Vpeak or dc
Maximum normal mode open circuit probe source voltage (at 132 Vrms line voltage): 8.6 Vrms, 12.1 Vpeak

Input Power Requirements

90 to 132 Volts rms
48 to 66 Hertz sine wave
Maximum Power: 396 Watts (3.0 Arms at 132 Vrms)

Check Resistor

Resistance: 100 milliohms ± 1%
Maximum continuous current: 17.5 Amps

Verification Schedule

There are no hardware calibration adjustments, and thus no hardware calibration is required or possible
Software calibration data is available, but it»s normally unnecessary to modify this data
Complete the formal performance verification procedure annually or following any repair service
