3. Application
Calibrate high-precision resistance meter
Establish a precision current measurement system
Standard resistance value transfer
☆ Calibrate standards/precision resistors
TH0330 can be used with precision resistor bridges such as TH0210 to achieve transfer calibration of standard resistors (first and second class).
☆ Establish a precision current measurement system
TH0330 can be used with DC I/I conversion standard (ratio standard) and precision voltmeter to form a precision DC current measurement system.
Note: When measuring current, the maximum operating current of the standard resistor should not be exceeded; for precision current measurement, the influence of factors such as the resistor's rated power and power coefficient should also be considered.
