Trek 323 高精度靜電電壓表
0 to ±100 V DC or Peak AC
• Sensitivity: 5 mV
• Speed of Response:
Less than 300 ms for a 100 V step
• Measurement Accuracy:
Better Than 0.05% of Full Scale
• Null Voltage Source:
10 Volt Nulling Supply
• Response Speed Control:
AC Response Adjusted for Speed/Noise
• Drift Spacing/Null
Adjustment: Minimizes Variations in voltage values as probe to test surface spacing changes
• Available Monitor Outputs:
1:1 of Voltage Monitor Output 10:1 or 20:1 (switch selectable)
• Additional Probes Available
The Model 323 has adjustments to compensate for many sensitive testing conditions. The response Speed control adjusts the speed/noise tradeoff of the AC response. The Drift/Spacing Null Adjustment minimizes the variation in zero offset voltage as the probe to test surface spacing changes.
The front panel has an easy to read 3½ digit LED display. The detected output voltage can be monitored through a 1:1 voltage monitor output and a switch selectable scale of 10:1 or 20:1 voltage monitor output.
Trek patented low impedance probes assure measurement accuracy essentially independent of probe-to-test-surface spacing, humidity conditions, and contamination such as airborne dust, toner, ions and chemicals.
