Description

The Elitech RC-51H features a durable and compact design, making it suitable for deployment in various environments. The device includes high-precision temperature and humidity sensors that provide accurate readings. It comes with a large LCD display that shows real-time data, allowing users to quickly check current conditions. The RC-51H also includes USB connectivity for easy data transfer to a computer, where data can be analyzed using the provided software.

The data logger can be configured to record data at customizable intervals, from as short as one second to as long as 24 hours. This flexibility makes it adaptable to different monitoring needs. Additionally, the device is battery-powered, ensuring that it can operate independently without the need for an external power source.

Parameter Instruction

Users can reconfigure the parameters by data management software per actual needs. The the original parameters and ata will be cleared.

Alarm threshold	This data logger supports 3 upper temperature limits, 2 lower temperature limits, 1 upper humidity limit, and 1 lower humidity limit.
Alarm zone	The zone which is beyond the alarm threshold.
Alarm type	Single: The data logger records the single time for continuous over-temperature events.
	Cumulative: The data logger records the cumulative time of all the over-temperature events.
Alarm delay	The data logger does not alarm immediately when the temperature is within the alarm zone. It begins to alarm only when the over-temperature time elapses the alarm delay time.
MKT	Mean kinetic temperature, which is an evaluation method of the temperature fluctuation effect on the goods in storage.

Operating Instructions

This data logger can be stopped by software. Users can stop the logger by clicking the stop button in the data management software.

Action	Parameter configuration	Operation	LCD indicator	Indicator

View data
When the data logger is inserted into the USB port of the computer, the data report will be created automatically. The red and green indicators flash in turn when the document is being created, and the LCD screen shows the progress of PDF Report creation. The red and green indicators light at the same time immediately after the document is created, then users can view the data report. The document creation will last for no more than 4 minutes.

Rotate the transparent cap in the direction of the arrow and remove it.
Insert the data logger into the computer and view the data report.
