The storage medium is non-volatile solid state memory, providing maximum data security even if the battery becomes discharged. Its small size allows it to fit almost anywhere. Data retrieval is simple. Plug it into an available USB port and the easy to use Windows[®] software does the rest. The software converts your PC into a real time strip chart recorder. Data can be printed in tabular format and can also be exported to a text or Microsoft Excel file for further calculations. As the leader in low power data logger technology, we continuously improve our products and develops solutions to meet ever-changing challenges. 

**Analog Conversion Time:** 133 ms nominal 

**Frequency Rejection:** 50 to 60 Hz **Temperature Coefficient:** 

< ±50 ppm/ºC typical 

The OM-CP-PROCESS101A is part of a series of low cost, state-of-theart data logging devices that has taken the lead in offering the most advanced, low cost, battery powered data loggers in the world today. The OM-CP-PROCESS101A is available in three ranges, 20 mA, ±160 mA and ±3A. All of the ranges offer a 10 year battery life, a 4 Hz reading rate, a multiple start/stop function, ultra-high speed download capability, 1 million reading storage capacity, optional memory wrap, battery life indicator, optional password protection, programmable high-low alarms and more. 

**Reading Rate:** 4 Hz to 1 reading every 24 hours 

**Memory:** 1,000,000 readings; software configurable memory wrap 333,000 readings in multiple start/ stop mode 

**Wrap Around:** Yes **Start Modes:** 

## • Immediate start 

- Delay start up to 18 months 

- Multiple pushbutton start/stop 

**Multiple Start/Stop Mode:** Start and stop the device multiple times without having to download data or communicate with a PC 

The OM-CP-PROCESS101A was designed with our customers in mind. There are free firmware upgrades for the life of the product so that data loggers already deployed in the field can grow with new technological developments. Units do not need to be returned to the factory for upgrades. The user can do this automatically from any PC. 

**Multiple Start/Stop Mode Activation:** 

Using the OM-CP-IFC200 software, starting, stopping and downloading from the OM-CP-PROCESS101A is simple and easy. Graphical, tabular and summary data is provided for analysis and data can be viewed in A, mA or µA. 

## **To Start the Device:** 

Press and hold the pushbutton for 5 seconds. The device has started logging. 

## **To Stop the Device:** 

Press and hold the pushbutton for 5 seconds, the red LED will flash for three seconds and then the green LED will flash for two seconds. The device has stopped logging
