• The four-wire wiring method can effectively eliminate the measurement error caused by the resistance of the test wire, and the measurement accuracy is higher;

• Compared with physical resistor boxes, analog resistors have the following advantages:

①The resistance value is continuously adjustable, with better adjustment fineness and better sensitivity;

②There is no influence from switching error, residual resistance error, contact resistance error, etc., and the measurement data is accurate and reliable;

③When the physical resistor is overloaded, it will cause the resistance to change value, and in severe cases, it may even cause the resistor to be damaged. TD1470 has current overload capability and impact resistance, and has been completely tested for electrostatic protection and electromagnetic compatibility. It has good protection performance and high reliability.

• TD1470 has a self-calibration function to ensure long-term accuracy and stability of the value.

• Large-size LCD screen: full color, high screen brightness, clear picture quality, and supports touch operation.

• Digit buttons: A variety of input methods such as fixed-point output, knob output, and step adjustment can be realized, and the operation is convenient and fast.

• Front panel wiring: It is convenient for users to replace the current and voltage test wires when checking the meter.

• The instrument has a "fixed point output" mode, through the digital button of the control panel or click the touch screen, directly set the required output value, the instrument will automatically switch to the best range output.

• When calibrating a resistance tester, it is usually necessary to select the calibration point according to the proportion of each range of the meter to be checked.

• The user can easily select the calibration point of the inspected meter through the "Percentage Output Button" on the console of this instrument or the "Percentage Check Point" on the touch screen.

• The operating area is equipped with a "Number Knob" that increases or decreases the output by rotating it clockwise or counterclockwise.
