1. Summary
TH0190 is a handheld precision AC current pressure gauge that can accurately measure the range of 20 mV ~ 10 V small-signal voltages, and the AC voltage measurement capability is better than 8-digit semi-high-precision standard digital multimeter.
2. Features
• Frequency range: DC, 40 Hz ~ 10 kHz.
• DC measurement uncertainty up to 30 ppm.
• Cross-current measurement uncertainty up to 50 ppm@53 Hz.
• 2~64th harmonic measurement, DC ripple measurement function.
• LCD color screen, digital button operation.
3. Applications
• Accurate measurement of AC and DC voltage and current on site
• Calibrate AC and DC voltage standard sources/meters, current standard sources/meters
☆ Measure the AC/DC voltage |
|
• It can be used with precision voltage divider (such as TH0150 / TH0170) formation of AC/DC voltage measurement system. • It can be used to measure the AC/DC voltage, AC/DC voltage source. |
☆ Measure AC-DC current |
|
• It can be used with I/V conversion standards (such as TH0400 / TH0500U) to form an AC/DC current measurement system. • It can be used for measuring AC/DC current signal, the calibration of AC/DC current source. |
4. Characteristics
☆ Measure ripple or distortion |
|
• The instrument supports DC, AC measurement mode, AC frequency range: 40 Hz ~ 10 kHz. • When measuring voltage, distortion and ripple measurements can be completed simultaneously, the maximum measurement bandwidth of DC ripple is up to 1 kHz, and AC supports the measurement of the 2nd ~ 64th harmonic. |
