Thiết bị đo tĩnh điện Prostat PDT-740B

Thiết bị đo tĩnh điện Prostat PDT-740B

Model: PDT-740B

Hãng sản xuất: Prostat

Thông số kỹ thuật:

OFF-ON Cut Off Voltage, 10, 50 and 100 Volts (Selects Voltage to stop timing)

Green LED: Decay Cycle Ready > ± 1kV, CPM voltage > ± 1,000 volts

Red LED: Timing in Progress, CPM voltage decay timing activated LOBAT displayed when battery voltage <6.0 volts

Display: Liquid Crystal Display (LCD) displays elapsed decay time from ± 1,000 volts to selected Cut Off voltage in seconds and tenths of a second (00.0)

Polarity: Automatically senses Positive & Negative voltage references

Zero & Reset: Automatically Resets Timer and Display to 00.0 when CPM voltage > ± 1kV. Reset indicated when Green LED Decay Cycle Ready LED is ON.

Response: Approximately 200 milliseconds in combination with the CPM-720 and PFM-711A

Timing Range: From 0.2 to 159.9 seconds

Timing Setpoints: Reset when voltage input 100mv ± 2mv (1,000 Field Meter Volts ± 20V)
Cut Off Voltage @ 100 V: 10mv ± 0.2mv (100 Field Meter Volts ± 2V)
Cut Off Voltage @ 50 V: 5mv ± 0.2mv (50 Field Meter Volts ± 2V)
Cut Off Voltage @ 10 V: 1mv ± 0.2mv (10 Field Meter Volts ± 2V)

Accuracy: Typically < ± 5%
