Specific Operating Methods of the Instrument Panel
◇This device is equipped with three buttons: "Select", "Confirm", and "Reset".
1. Resistance Measurement
After powering on or pressing the reset button, the instrument enters the initial state (1). At this time, the cursor pointer points to "Resistance". Press the "Confirm" button directly to enter state (2), which displays the changing charging current and measurement time. After charging is completed, it automatically enters state (3), displaying the resistance value, measurement current, and measurement time. At this point, each press of the "Confirm" button stores a measurement result (models with a printer will simultaneously print the measurement result). Press the "Reset" button to exit resistance measurement and enter state (4), which displays the discharge current. After discharge ends, it automatically returns to the initial state (1), completing one resistance measurement.
2. Number Setting
Inputting the device number helps in searching memory data. In the initial state (1), point the cursor to "Setting" and press the "Confirm" button to enter state (5), which displays the current device number. Press the "Confirm" button again to enter state (6), prompting for a new device number. At this time, pressing the "Select" button cycles the current input digit from '0' to '9', then from 'A' to 'Z'. After finding the desired number or letter, press the "Confirm" button to input that digit. Then input the next digit using the same method. After entering six digits, it returns to state (5), displaying the newly entered device number. Press the "Reset" button to return to the initial state (1).
3. Memory Operation
In the initial state (1), move the cursor to "Memory" and press the "Confirm" button to enter state (7), which displays the total number of records in the current memory. At this time, pressing the "Select" button enters state (8), displaying the memory records starting from the most recent one. NNNNNN represents the device number of that record, and MM represents the MM-th resistance value of that device. During measurement, each press of the "Confirm" button to store a measurement result increments the MM value by 1. Each time a new device number is entered, the MM value restarts from 1. Pressing both the "Select" and "Confirm" buttons simultaneously will clear all data in the memory. Press the "Reset" button to exit the memory operation and return to state (1). The memory can store up to 120 measurement results, and after exceeding 120, the oldest records will be overwritten. The memory content can be retained for a long time without loss even when power is off.
