Main features of the lightning protection element tester:
(1) Suitable for testing DC parameters of overvoltage protection components such as zinc oxide arresters (varistors), metal-ceramic two- and three-electrode discharge tubes, and vacuum lightning arresters.
(2) Equipped with high-voltage short-circuit protection, overcurrent protection, high-voltage presetting, and range adjustment functions.
(3) Has self-check and discrimination functions, providing audible alerts for over-range measurements during testing.
(4) Features memory, calculation, hold, control, and continuous testing functions.
(5) Test results are displayed on a 3 1/2-digit LCD, automatically showing accurate and reliable required data.
Preparation
1. Set all self-locking button switches on the instrument panel to the high position, turn the "High Voltage Limit" knob clockwise to the end (maximum), and turn the "Voltage Preset" knob counterclockwise to the end (minimum). Insert the provided test leads into the "+" and "-" test jacks on the panel. Connect the external power supply to the corresponding power socket (jack) on the back panel.
2. Turn on the power switch. If the instrument displays "000", it indicates the instrument is normal. Otherwise, it is abnormal; please contact after-sales personnel promptly.
