Frequently Asked Questions
How to determine if the instrument ports are normal?
+
-
The instrument has twelve break points, each of which can be used independently.
① When no break point test line is connected, the circuit is in the open state, and the test interface will also display "Open". If one phase of a break point displays "Closed", it indicates a fault in that break point. In this case, switch to another break point for testing.
② Connect the break point test line and short-circuit the yellow, green, red, and black (common) terminals. The break point status will change from "Open" to "Closed", indicating normal operation.
When grounding the instrument in the field, why should the grounding wire be connected first, and then the break point wire connected?
+
-
Because during field testing, the break point of a high-voltage switch (especially above 220kV) often has a very high induced voltage between the break point and ground. While the voltage value is large and the energy is relatively small, it is sufficient to threaten the safety of the instrument itself. Internally, the instrument has a discharge circuit between the break point signal input terminal and ground. Therefore, grounding the wire first prioritizes connecting the discharge circuit. When the break signal line is connected at this point, even if a high voltage is induced at the break point, it can be discharged to ground through the discharge circuit, thus ensuring the safety of the instrument's break channel.
What if the printing paper is installed backwards?
+
-
Open the integrated printer and correctly reinstall the thermal printing paper.
