Whilst the C53 is designed for ease of use, a number of advanced functions make it very versatile and suitable for use in a wide range of applications including research and development. A passcode protected setup menu allows the C53 operation to be fully customised to cater for all uses. The setup menu also allows settings such as test speed and displayed units to be changed.

In use the tablet is placed in the loading area between two jaws (platen and plunger). The left hand stationary platen is attached to a precision strain gauged load cell. The right hand plunger is motorised and crushes the tablet between the jaws. Tablet fracture is automatically detected and the fracture load (hardness) is displayed on the LCD.
Meanwhile the plunger returns to its preset position ready for another test and the internal printer prints the hardness, along with the weight and thickness if a weigh balance and / or calliper are connected. Results are also displayed on a connected PC if desired. The tablet fragments are collected in a tray situated underneath the loading platform. When testing of the batch is complete the STATISTICS button can be pressed to print statistical data for the batch.
New tablet sizes are set by pressing the NEW SIZE button, inserting a tablet, and then pressing the TEST button. The new size is automatically detected and the machine is ready to test the new batch. If desired the tablet diameter is measured and printed, along with product details & operator ID.
The plunger operates at two speeds, test speed and full speed. Test speed is adjustable and can be set between 4 and 50mm/min. Full speed is approx. 130mm/min. When testing, full forward speed is applied to the plunger until the tablet diameter is reached, test speed is then applied until tablet fracture is detected, full reverse speed is then applied to the plunger and it returns to its preset position. If desired the test can be started by closing the safety guard rather
