FULL If a single memory is full of 500 groups and continues to measure, the screen will display "FULL" and no more data will be stored. Indicates that the current measurement result is judged as FAIL failed. Indicates that the current measurement result is judged as a WARNING. Indicates that the current measurement result is judged as PASS passed. Indicates that the current measurement result has subtracted the initial line resistance.
constant, but NTC changes its resistance with temperature changes, and the actual temperature value is obtained by measuring the partial pressure voltage and bringing it into the NTC temperature conversion formula. VIII. Operation Method 8.1 Power on /off and automatic shutdown ● Press to power on /off. ● If the automatic shutdown function is turned on, and no key is pressed within 15 minutes after starting up, the meter will automatically shut down to save power.
The alarm setting interface can set the buzzer prompt mode when the test is completed.
8.4 Measurement procedure Internal resistance measurement: 1) Connect the test line to the meter, and connect the indication mark (small arrow) of the test line and the indication mark (small arrow) on the machine according to the corresponding color. 2) Set the instrument parameters, refer to 8.3.1 and 8.3.2. 3) If you use a test line other than the standard configuration, short-circuit the four-wire clamp of the test line, and then press the key to adjust the zero calibration.
records, which can visually analyze the internal resistance of the batch of batteries. You can use the or to move the reading cursor left and right. The item selected by the cursor can read the specific information of battery internal resistance, voltage, temperature and test time. You can also use the or to scroll through pages. Figure 8-1 Histogram interface 8.7 Communication with PC Please confirm before use: 1. The USB driver has been installed. 2. EXCEL software is installed in the computer. 3.
2) Charging is about 5 hours from to electric charge. Whether the battery is fully charged depends on the charging indicator. The red light means charging, and the green light means it is fully charged.
What capacity (Ah) battery internal resistance and voltage can be measured? This meter uses AC signals for measurement, and DC current does not flow into the meter. Therefore, there is no restriction on the capacity (Ah) of the battery under test. X. Packing List Meter 1pcs Test lead 1 set USB cable 1pcs Power adapter 1pcs Manual 1pcs Instrument box 1pcs Note: The monitoring software can be downloaded from Uni-trend official website.
Appendix 2 Extending the test lead and the influence of induced voltage The quality and structure of the test cable have a certain impact on the measurement results. If you need to extend the test cable, please use the test cable recommended by our company. How to reduce induced voltage Since this meter uses AC to measure small resistance, it is susceptible to the influence of induced voltage.
