Instrument setup parameters and operation instructions:

1. Range:Enter the instrument test range in the program based on the pressure sensor's measurement range.

2. Instrument Calibration:Set the calibration value on the program for adjustment, then place the corresponding standard code, and the displayed value matches the calibration code.

3. Sensitivity: Due to the measurement samples from the customer being both soft and hard, The required sensitivity may not match what we need.Instrument sensitivity is divided into 1-19 levels, with higher numbers indicating greater sensitivity. Generally, level 16 is chosen, but please adjust according to specific circumstances.

4. Language:The instruments have been exported in bulk, with language options for both Chinese and English display and printed output.

5. Print:Print the corresponding strength values in the order of measurement.

6.Average value shows:The same measurement sample must be measured more than 10 times to display the average value. Values with fluctuations exceeding 60% of the average will be automatically excluded. The average value (avr) will be displayed at the end of the printed results.
