PDT-740B 靜電衰減計時器

測量負離子空氣淨化器的衰減時間

PDT-740B靜電衰減計時器是PROSTAT最新技術的產品，為ESD 管理和 ESD 監查提供可靠的技術支援。

這一獨特的儀器主要用於測試在離子消散機作用下，靜電電壓從 ±1,000伏特到小於100伏特內靜電的衰減時間，此測試方法符合ESD美國防靜電協會有關離子中和標準S-3.1；測試防靜電材料靜電電壓從±1,000伏特到小於50或10伏特的衰減時間。

離子消散機性能和測量防靜電包裝材料

配合其它相關設備，PDT-740B可評估離子消散機性能和測量防靜電包裝材料、防靜電鞋、人體防靜電接地、防靜電生產輔助設備、防靜電儀器及許多其他的需ESD控制產品的靜電衰減時間。

通過使用PGB-745測量材料

對於測試其它防靜電材料或產品，我們推薦使用其它特定的配件，如PGB-745靜電衰減測量電極，或、PRF-911同心環電極夾具。

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

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)

Automatically senses Positive & Negative voltage references

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

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

From 0.2 to 159.9 seconds

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)

Typically < ± 5%
