Appendix 1: Method for Replacing Paper in the 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. Press the movable tabs on both sides of the printer inward with your fingers, 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 spindle from the printer.
(4) Slide the new paper roll onto the spindle, and install the spindle 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, use your hand to feed the paper head into the paper inlet below the print head. The paper will quickly enter the print head until it emerges from the front of the print head. Ensure that the exposed part has a certain length, then press the SEL or LF key again to stop paper feeding. Turn off the power, close 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 the DC Resistance Tester:
Close the main power switch, and the corresponding indicator light will turn on. Press the "Start/Stop" key to begin the test. After the test is completed, press the "Reset" key. 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 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 operation.
Special Attention: 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.
