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).

FAQ
1.Q: Can the LS-ER200 be customized (e.g., power supply or communication interface)?
A: Yes, we support full customization. You can choose between 220VAC or 12VDC power supply, and adjust RS485 parameters (baud rate, address) or alarm thresholds to match your system.
2.Q: What is the MOQ? Can we place a small trial order?
A: We accept small trial orders with a standard MOQ of 1 unit, supporting both sample and bulk purchases.
3.Q: How long is the lead time? Can we get priority production for urgent projects?
A: Standard lead time is 7-15 working days. We can arrange priority production for urgent orders to meet your project schedule.
4.Q: What is the warranty period? How do you handle after-sales issues?
A: We offer a 2-3 year warranty. Non-human-caused failures within the warranty period can be replaced or repaired free of charge.
5.Q: Can we get test samples? How are sample fees and shipping costs calculated?
A: Test samples are available. Sample fees are required in advance and can be deducted from bulk order payments. Shipping costs are usually collected separately or negotiated.
