4 Test method
4.1 Check the power supply of the instrument
SY 534889
Press the power button switch, adjust the calibration knob, and adjust the pointer to the calibration position. If it cannot be adjusted to the calibration position, check the power supply or replace the battery.
4.2 Check the size of the resistance pool
Use a length measuring instrument with an accuracy of 0.02mm to check, which should comply with 3.2.1, b, c, 4.3 Thermometer
The capillary tube is intact and the mercury has no broken wire, and check the factory certificate. 4.4 Instruments and samples required for the test are shown in Table 1.
4.5 Range and error check

Three kinds of fluids tested for the test:
1, 0.1. 0.5mol
4.5.! Calibrate the instrument: Press the power button switch: Adjust the calibration knob so that the meter pointer points to the calibration position. 200mL each
4.5.2 Replace the resistance box with the two electrodes of the resistance cell of the resistivity meter, adjust the resistance box to different resistance values, and press the button at the same time. The indication value of the resistivity meter should correspond to the indication value of the resistance box, as shown in Table 2. Its range and error should meet the requirements of Article 3.2.2.

The result of the delivery inspection is significantly different from that of the most recent type inspection: the national quality supervision agency has proposed the requirements for type inspection.
5.2 Judgment rules
Test method clauses
4.2 ~ 4.3bzxz.net
Each instrument shall be inspected one by one according to the delivery inspection items before leaving the factory. If one of the items is unqualified, it shall be deemed unqualified, but repair is allowed.
SY5348—89
Type inspection shall select samples from the qualified products in the factory inspection. The number of samples shall not be less than 3. If all the inspection items in the selected samples are qualified, the type inspection of this batch of products shall be qualified. If there are unqualified items in the inspection results (the total number of unqualified items shall not exceed two, and no abnormal items occur), then samples twice the number of the first random inspection may be selected for re-inspection. If all the total inspection results are qualified, the type inspection of this batch of products shall be considered qualified.
