The intelligent inspection instrument is suitable for detecting and alarming process quantities from 5 to 80 points. Can input sensor and transmitter signals such as thermal resistance, thermocouple, DC current, DC voltage, etc.

Basic error less than 0.2% F · S, display range -1999~9999

Set input signal type, range, and alarm value for each channel

Set digital filtering time constants for each channel to effectively improve anti-interference ability

Set zero and full scale corrections for each channel, effectively reducing sensor errors and improving system measurement accuracy

Can close unused channels at will

Level 2 parameters. The second level parameters are password controlled to prevent accidental operations. Equipped with parameter copying function, greatly reducing the workload of parameter settings

Extremely practical alarm function, can be connected to multi-point control units to achieve alarm output for each channel

Manual, timed, and alarm start printing

Quick and effective communication interface, greatly reducing communication time

2、 Selection table for intelligent inspection equipment:

Note: Matching can achieve alarm output for each channel. Each unit * * has an additional 16 control outputs, and each meter * * can use up to 2 to achieve 32 point control.

The multi-point control unit is used in conjunction with the inspection instrument, and through the matching multi-point control unit, the alarm status of each channel can be directly output or combined output.

To achieve the purpose of alarm or control for each channel.

Note: 1. The standard configuration includes 4-point control

2. All 16 control points can be selected as relay outputs or solid-state outputs, or different control outputs can be corresponding to different points, but they should be specified when ordering.
