3. Applications
☆ Calibration for DC High Voltage / High Resistance Unit |
|
• Application 1: With CV and CC two modes to measure the DC resistance in the wide ranges of 100Ω~ 10 TΩ. It can measure the residual resistance, switch contact resistance variation, basic error, voltage variation and other items. • Application 2: It can directly output 1 V to 10 kV DC voltage for calibrating DC high voltage meter. • Application 3: With a digital voltmeter, it can calibrate V/V conversion devices such as DC high voltage dividers, high voltage probes, and voltage transformers. |
4. Characteristics
☆ CV/CC Mode to Measure DC Resistance |
|
• CV mode: TD1210 can output up to 10 kV for high value resistance measurement. Equipotential shield protection design at the low end of output, which can reduce the leakage current and improve the accuracy of measurement. • CC mode: TD1210 can output small current for low resistance measurement, which can help prevent high voltage damage on low resistance disk. • Users can customize the output voltage or current value according the resistance range. |
☆ Statistical Analysis |
|
• Data statistical analysis start with start key and test in loop continuously. It shows the max value, min value, peak-peak value, average value, standard variance etc. |
☆ Multiple Output Mode |
|
• “Direct output”mode，User can set output value by physical key or touch screen. |
|
• “Rotary Knob”mode，User can setting in clockwise direction or anticlockwise direction. |
☆ Multiple Output Mode |
|
• Touch “Calibration point”of screen for “% setting”. |
