Figure 7-4 Calibrator channels display
Notice: The calibration fixture selected must correspond to the channel in the device list bar one
by one.
4. Resistance of the shunt of calibrator
The resistance value is the default value and cannot be modified. If the calibration fails, the administrator can modify
the calibration. When you select the calibration tool, the modification permission is enabled, as shown in Figure 7-5.
Calibration separator: In order to ensure the correct result of automatic calibration and the accuracy can reach the
expected goal, the shunt of the automatic calibration tool should be calibrated regularly before using it.
1 Users can prepare an additional calibrated multi-meter, with the red and black multi-meter pen connected current
cathode and anode.
2 The on-board channel of the calibration fixture is used to execute CC, and the multi-meter paired with the
calibration fixture is used to measure the voltage at both ends of the shunt.
3 From the measured current value and voltage to calculate the actual resistance value.
5. Temperature and humidity
You can set the temperature and humidity based on actual conditions, as shown in Figure 7-6:

Calibration Mode
Users can select the corresponding calibration mode and current/voltage calibration section number as required.
1. Calibration mode:
Calibration, Accuracy test, Cali and accuracy, accuracy cali and accuracy again, as figure below:
Figure 7-7 Calibration mode and segments
Calibration: After the user selects the channel to be calibrated and sets the calibration parameters, each calibration
point is automatically sampled and calculated, and the calculated KB value is written to the lower-machine. During
calibration, only the selected channel will be calibrated.
Accuracy test: After the user sets the channel to be calibrated and the parameters, each calibration point of each
channel is automatically sampled and calculated, and the control precision or measurement precision is comparing with
the required precision to determine whether the channel meets the accuracy requirements. During calibration, only
high-precision test of channels is operating.
Calibration first, then test accuracy: After the user selects the channel and sets the parameters, the system will start
the calibration automatically. After the calibration is completed, the automatic accuracy test will continue.
Test accuracy first, then calibration: After the user sets the channel to be operated and also the parameters, the
system will automatically starts to test the accuracy of all channels, then calibrates and rechecks each channels.
2. Segments of calibration
Calibration point: Calibrate the equipment in segments according to the range percentage, and each upper and lower
range percentage in each section is a calibration point.
Segments: The equipment range is segmented by percentage, and there is a segment between each adjacent calibration
point. If the number of calibration points is N and the number of calibration segments is M, then M =n-1. The details
are described below:
1 In "calibration" mode, the current calibration points and voltage calibration points are "3-stage calibration" and
cannot be modified.
2 In the "Precision test" calibration mode, the current calibration points and voltage calibration points are both set to
"3-section calibration" by default, and the calibration points can also be modified to "9-section calibration" at
