Product description
|
|
● Flexible mounting & standard protocol: Supports 35mm DIN rail mounting and flat panel mounting, equipped with a 1-inch OLED display and compliant with MODBUS-RTU communication protocol.
|
|
● 1-group EPIC test terminal: Designed for connecting grounding electrodes, voltage test electrodes, and current test electrodes respectively.
|
|
● Multiple measurement principles: Adopts three-pole method, two-pole method, and voltage-current method for comprehensive testing.
|
|
● Precise resistance measurement: Capable of measuring maximum/minimum/average grounding resistance, with a measurement range of 0~200Ω and 0.01Ω resolution.
|
|
● Dual power supply options: Supports both DC 12V and AC 220V power input for flexible deployment.
|
|
● Automatic isolation switch: Built-in isolation switch on the EPIC port, which automatically turns on during testing and off after completion.
|
|
● Intuitive status indication: Features power supply, test, and communication indicators, plus a manual test button for on-demand operation.
|
|
● Audible alarm function: Built-in buzzer that triggers an alarm when the measured resistance exceeds the preset threshold (alarm value configurable).
