☆ Output and Adjustment

TD1000 Calibration Apparatus for Clamp Meters Output and Adjustment

The device has a " Direct output " mode. By clicking the touch screen, you can directly set the required output value. The device will automatically switch to the optimal range output, making it very convenient to calibrate digital instruments.
Especially when setting the AC voltage/current output, you can directly enter the amplitude and frequency at the same time, which is very convenient to use.

TD1000 Calibration Apparatus for Clamp Meters Calibration of the analog pointer meter

The calibration of analog pointer type usually needs to be carried out scale by scale, especially the "rising and falling variation" (i.e. the change caused by the rise and fall of the tested point), and the output of the source needs to be adjusted to align the indicator of the tested table with the graduation line of the tested point.
It is relatively inconvenient to use the digital fixed-point output method to adjust the output of the standard source to achieve the alignment of the scale.
For this reason, we provide users with a remote box (optional accessory). Through the operation of coarse adjustment-fine adjustment, the output can be quickly adjusted to align with the scale of the tested table, which is very convenient to complete the calibration of the analog table. This function is particularly useful when it is necessary to consider the friction or hysteresis effect during movement.
