1. Summary
TH1200 is an instrument that uses the standard source method to calibrate the nanovoltmeter, and is also suitable for calibrating the voltage-measurement function of DC shunt verification device, small signal voltage-measurement function of DC energy reference standard and other equipment.
2. Features
• Standard voltage output：1 μV～110 V
• Uncertainty of measurement 6 ppm@10 V.
• Typical stability at mV output：10 nV/min.
• 8-digital，minimun resolution：1 nV.
• LEMO interface for 2-channel voltage output.
• Constant temperature control technology to reduce the environmental fator
• Specific test wire
• Specific automatic calibration software（optional）
3. Application
☆ Standard source method to calibrate the nanovoltmeter |
|
• Calibrate 2-chanel voltage simultaneously：1 μV～110 V（CH1）& 1 mV～11 V（CH2）。 • Meet Calibration requirements of nanovoltmeter（such as Agilent 34420A、Keithley 2182A） |
☆ Interface and Automatic Calibration Software |
• support RS232、LAN、USB，and accept customer requirements for software function customization。 |
