• TD1210 features a built-in wideband constant current source ranging from 2 μA to 21 mA, enabling direct verification of leakage current error using the standard source method.

• The constant current source supports a wide frequency range from DC, AC 10 Hz–3 kHz, meeting the frequency verification requirements for both general and medical leakage current testers.

• Built-in AC standard voltmeter enables verification of test voltage error and distortion in accordance with regulations.

• Features data statistical analysis, allowing measurement of maximum value (Max), minimum value (Min), peak-to-peak value (P-P), average value (Avg), and standard deviation (S.dev) to comprehensively assess AC voltage source performance.

• Compared to a standalone digital voltmeter, it offers a higher level of integration, simplified wiring, and more convenient operation.

• The verification of the DUT measurement network includes DC input resistance, input impedance, and transmission characteristics/transmission impedance measurements.

• DC Input Resistance: The built-in wideband constant current source outputs DC current to the DUT with the human body impedance network applied. The loop voltage is then measured to calculate the DC input resistance of the measurement network.

• Input Impedance Measurement: Supports frequency sweep testing of the impedance network. The wideband constant current source outputs current at incrementally increasing frequencies, and the loop voltage is measured to determine the input impedance at different frequencies.

• Transmission Characteristics Measurement: The built-in wideband constant voltage source outputs a standard voltage to the DUT with the human body impedance network applied. By referencing the KV lookup table, the standard leakage current I₀ is obtained. Comparing this with the DUT’s displayed current value allows verification of transmission characteristics.

• Transmission Impedance Measurement: The built-in wideband constant voltage source outputs a standard voltage to the DUT with the human body impedance network applied. The transmission impedance value is calculated based on the ratio of the network's input standard voltage to the output voltage reading.

• Large LCD Screen: High-brightness, full-color display with clear image quality; supports touch operation for comprehensive functionality and ease of use.

• Digital Programmable Keys: Enables multiple input methods, including direct output, rotary knob, and step adjustment, ensuring convenient and efficient operation.

• Optimized Terminals: Designed to minimize the need for frequent test lead changes during calibration, enhancing operational convenience.

• Lightweight Design: ½ 3U standard chassis weighing less than 9 kg, making it compact, lightweight, and ideal for on-site applications.

• High Integration: Combines a wideband constant current source, wideband constant voltage source, DC resistance meter, impedance tester, AC voltage meter, and distortion analyzer into a single instrument. Compared to single-function testers, this high level of integration simplifies wiring, enhances ease of operation, reduces initial investment costs, and significantly improves testing efficiency.
