Electrostatic Voltmeter for EOS/ESD - Model 542A
Trek Model 542A Non-Contacting
ファイルをダウンロード 製品のお問い合わせThe Trek Model 542A Electrostatic Voltmeter (pictured at left with the Model 542P-S probe) provides accurate non-contacting measurements of the electrostatic surface voltage associated with EOS/ESD processes. The instrument is configured with a miniature electrostatic field chopper probe that can be remotely located and easily positioned within process equipment to provide highly accurate, non-contacting, DC-stable, spacing-independent voltage measurements in either ionized or non-ionized environments. A 20x4 alphanumeric LCD screen displays the present measured voltage, the positive peak voltage value, the negative peak voltage value and additional menu information.
Typical Applications Include :
- Semiconductor
- LCD
- Electronic Assembly
- ESD-Sensitive Process
Specifications:
| Measurement Range | |
| Model 542A-1 : | ±10 kV DC or peak AC |
| Model 542A-2 : | ±20 kV DC or peak AC |
| Measurement Accuracy : | Better than ±5% of the reading ±0.2% of full scale over a probe-to surface separation of Model 542A-1 (15 mm to 30 mm) / Model 542A-2 (30 mm to 60 mm) |
| Alphanumeric LCD Display : | 20 x 4 characters |
