• 2-terminals and 4-terminals resistance wiring mode. When calibrating the low value resistance, the four wire system wiring mode can effectively eliminate the measurement error caused by the resistance of the test lead and improve the measurement accuracy.

• Compared with the standard physical resistance box, the analog resistance output has the following characteristics:

☑ Continuously adjustable, with better adjustment fineness and sensitivity

☑ Smaller size and lighter weight

☑No influence of transfer switch error, residual resistance error and contact resistance error.

• Calibration of the analog pointer meter usually needs to test scale by scale, especially "differences between rising and falling" (the change caused by the rise and fall of the calibration point).

• Remote box can realize the coarse and fine adjustment of current or voltage.

• “Rotary Knob” mode, User can set in clockwise direction or anticlockwise direction.

• Use the key ↑10%、↓10%、×10、÷10 on the front panel, can realize the adjustment of the quantity value, and can also be used to perform the relevant test of linearity.
