Elitech DR-230 Temperature and Humidity Recorder Instructions

Product Overview

The DR-230 series is a large screen temperature and humidity recorder used for real-time monitoring and recording of ambient temperature and humidity. It supports functions such as over-limit alarm and historical data upload. The recorder consists of an external temperature and humidity sensor and host equipment. Users interact with the recorder via the Jingchuang Cold Cloud APP. Operating parameters, including temperature unit, time zone, recording interval, alarm switch, alarm parameters, and sensor type, can be set through the APP. Recorded data stored in the recorder can be read via the APP and automatically uploaded to the cloud. Historical data can also be accessed through the APP for report export and other operations. The product is widely used in industrial workshops, warehouses, and similar scenarios.

1. Product Features

2. Product Interface

The device display shows: ① Measurement channel, ② Real-time temperature (°C), ③ Current time, ④ Real-time humidity (%RH).

Measurement Channel

When the device is configured with an external sensor type, the data from the first external T/H sensor is displayed (indicated by '1------'), followed by the data from the second external T/H sensor (indicated by '2------'). If the device is configured with a built-in sensor type, the channel indicator is not displayed, and the current display data is from the built-in sensor.

Alarm Display

When any measured temperature or humidity value exceeds the limit, the device flashes the full screen at a 1-second interval. When the measurement value returns to the normal range, the device automatically restores the steady on display.

3. Product Structure

The back of the device shows: ① wall hanging hole, ② Equipment information.

Manual

Peripheral Connections

According to the interface icons on the back of the recorder, connect the corresponding peripherals (power supply, sensor, alarm).

Power Supply

Use the standard power cord to connect the recorder for power supply. The device will turn on automatically after power-on.

Configuration

Use the Elitech iCold APP to set the recorder parameters. During the recording process, if parameter changes are needed, stop the recording and then re-pair the device. Note: After reconfiguration, the original data will be cleared.

Alarm

1. The Elitech iCold APP can be used to configure device alarm parameters, including temperature alarm upper limit, temperature alarm lower limit, humidity alarm upper limit, humidity alarm lower limit, alarm mode, and alarm switch.
2. When any measurement parameter of temperature or humidity exceeds the limit, the device flashes the screen every 1 second. When the temperature and humidity value returns to the limited range, the device automatically returns to normal display.
3. When any temperature and humidity measurement parameter exceeds the limit, the device will start timing according to the alarm delay time setting. If the temperature and humidity measurement value does not return to normal within the delay time, it will alarm according to the set alarm mode after the delay time is up (external acousto-visual alarm).
