Installation guide for the Agilent 7820A gas chromatograph, covering tools, setup, cable connections, IP configuration, and data system installation.
This document provides step‑by‑step instructions for installing the Agilent 7820A gas chromatograph. It lists the required tools and parts, describes site preparation, and specifies the hardware and software prerequisites, including the need for a PC with administrative rights and the Agilent Instrument Utility.
The guide walks the user through connecting calibration gas, wiring cables, setting the instrument and PC IP addresses, installing the data system, and configuring remote start/stop cables. It also includes information on connecting both Agilent and non‑Agilent devices and the electrical specifications for the APG remote signal. This manual is written in Chinese.
| Typical APG remote signal voltage | 3 V |
|---|---|
| Low‑logic voltage threshold | < 0.4 V |
| High‑logic voltage threshold | > 2.2 V |
| Pull‑up resistor range for APG signal | 1 kΩ – 1.5 kΩ |
| Minimum current for low‑logic state | 3.3 mA |
| Maximum number of instruments synchronized with remote cable | 10 |
Up to ten instruments can be synchronized with the cable.
A pull‑up resistor of approximately 1 kΩ to 1.5 kΩ is required.
The minimum current is 3.3 mA per device.
