Quick start guide for assembling, configuring, and calibrating the H770 magnetostrictive level meter.
This guide walks you through the assembly of the H770 magnetostrictive level meter, connecting it to a test system, and configuring key parameters such as float polarity, signal threshold, and range settings. It also covers user calibration procedures and LCD display options.
Additional sections explain fault codes, troubleshooting steps, and detailed button functions, helping users maintain reliable operation of the level gauge in industrial applications. This manual is written in Chinese.
| Communication resistor | 200~500 Ω |
|---|---|
| Signal threshold | 200 mV |
| Upper dead zone | >120 mm |
| Float polarity | N‑pole up or inward |
| LCD output current (alarm low) | 3.8 mA |
The power circuit must include a communication resistor of 200 to 500 Ω.
Press the S key to cycle through the variables (current, percentage, main variable, temperature) and release the key when the desired variable appears.
Alarm E30 means the first float was not detected (no signal).
