The measurement parameters are easy to program. The recording is made directly on an internal 32 GB memory card. The DAS240 is composed with a main base frame and extension modules of 20 channels each. The DAS220 is composed with a main base frame and 10 analog inputs are integrated. -
Page 11: Recording Period
2.1.1. Recording period The acquisition on each valid channel is done every millisecond, For each channel one can choose a sampling period variable from 1 ms to 100 ms ( for Pt100 and Pt1000 3 wires : the period is variable from 2ms to 200ms.) This period of integration can eliminate noise for high frequency Example : main noise at 50Hz or engine noise at 1kHz. -

For a given range of temperature measurement, the software calculates the voltage caliber the following way: * Let « T » the absolute value of the max. measurable value, in °C * Add 40°C to take the max. - Page 78 Measurement accuracy: Pm The measurement accuracy Pm depends on the voltage range of the appliance (see the previous paragraph) and on the slope of the thermocouple.
