The RD45A single channel and RD46A dual channel flatbed recorders are ideal instruments for use in research, development and production, as well as in service and education applications. Designed for ease of use, these recorders have an ergonomic shape which allows the user to easily write comments on the chart, even next to the pen.

The wide, 200 mm (8") chart is capable of recording measurements from 1 mV full scale to 20 V. Chart speeds from 0.1 mm/min to 20 mm/sec (1 mm = 0.03937") are available. The electric pen lift function will automatically lift the pens if the chart has not been advanced for 30 seconds; this will lengthen pen life, as well as keep the chart paper clean and easy to read.

The RD45A and RD46A have built-in HOME and GRID functions.
The home function is useful for comparative measurements, where the chart is rewound automatically to the same starting point. The grid function moves the pen to an exact grid line on the chart, which allows for easy repetitive measurements. As an option, pen offset compensation is available. This eliminates the recording offset caused by the distance between the two pens.
