Appendix 1: Method for Replacing Paper in Panel Printer

The printer equipped with the instrument has been installed with a paper roll at the factory. When the paper roll inside the printer is used up, a new paper roll needs to be installed. The specific installation process is as follows:

(1) Remove the front cover of the printer.

(2) Remove the entire printer from the instrument panel. Use your fingers to press the movable tabs on both sides of the printer inward, and gently lift the entire printer off the instrument panel. Note: Before removing the printer, make sure the printer power is turned off.

(3) Remove the paper roll shaft from the printer.

(4) Slide the new paper roll onto the paper roll shaft, and install the paper roll shaft into the guide slot of the printer so that it will not fall out.

(5) Cut the paper head into a cone shape.

(6) Turn on the printer power, press the SEL key to turn off the SEL indicator light, then press the LF key to rotate the print head. At this time, manually feed the paper head into the paper inlet at the bottom of the print head, and the paper will quickly enter the print head until it emerges from the front of the print head. The exposed part should have a certain length. Press the SEL or LF key again to stop paper feeding. Turn off the power, cover the front cover of the printer, and thread the paper head out through the outlet on the front cover.

(7) Reinstall the entire printer onto the instrument panel.

Usage Method of DC Resistance Tester:

A: DC Power Supply Test:

Close the main power switch of the DC resistance tester, and the corresponding indicator light will turn on. Press the "Start/Stop" key to perform the test. After the test is completed, press the "Reset" key, and the instrument will display "Discharging". Wait until the instrument returns to the startup interface, then turn off the main power switch, and the corresponding indicator light will turn off. Then switch the test clips for another test.

B. AC Power Supply Test:

Connect the AC 220V power supply, and the "Charging" indicator light will turn on. Close the main power switch. The specific operation is the same as the DC power supply operation.

Special Note: After the test is completed, you must press the "Reset" key and wait until the instrument returns to the startup interface before turning off the power for the next test.

Specific Operation Methods of the Instrument Panel

◇This instrument has three keys: "Select", "Confirm", and "Reset".

1. Resistance Measurement

After the instrument is turned on or the Reset key is pressed, it enters the initial state (1). At this time, the cursor pointer points to "Resistance". Press the "Confirm" key directly to enter state (2), displaying 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 time, each press of the "Confirm" key stores a measurement result (for models with a printer, the measurement result is also printed). Press the "Reset" key to exit resistance measurement and enter state (4), displaying the discharge current. After discharging is completed, it automatically returns to the initial state (1), completing one resistance measurement.

2. Number Setting

Entering the device number helps in searching data in the memory. In the initial state (1), move the cursor pointer to "Setting" and press the "Confirm" key to enter state (5), displaying the current device number. Press the "Confirm" key again to enter state (6), prompting to input a new device number. At this time, pressing the "Select" key can cycle the current input digit from '0' to '9', then from 'A' to 'Z'. After finding the desired number or letter, press the "Confirm" key to input that digit, and then input the next digit in the same way. After inputting six digits, it returns to state (5), displaying the newly input device number. Press the "Reset" key to return to the initial state (1).

3. Memory Operation

In the initial state (1), move the cursor to "Memory" and press the "Confirm" key to enter state (7), displaying the total number of records in the current memory. At this time, pressing the "Select" key can enter state (8), displaying the memory records starting from the latest record. NNNNNN represents the device number of that record, and MM represents the MM-th resistance value of that device. During the measurement process, each time the "Confirm" key is pressed to store a measurement result, the MM value increases by 1. Each time a new device number is input, the MM value starts accumulating from 1 again. Pressing the "Select" and "Confirm" keys simultaneously will clear all data in the memory. Press the "Reset" key to exit the memory operation and return to state (1). The memory can store up to 120 measurement results. After exceeding 120, the oldest records will be overwritten. The memory content can be retained for a long time without loss even when the power is off.
