NA_ENR_DAS240_CONF_VOIE Version: 1 SETTING A CHANNEL DAS240 The recorder DAS240, enable to record the following settings: voltage, current, resistance, temperature (with a thermocouple, PT100 or PT1000). We are going to see how to set an acquisition channel, with three examples: 1) Channel 1 configuration with a single voltage 2) Channel 2configuration with a K type thermocouple to measure an ambient temperature 3) Current configuration with a SHUNT resistor...

3- Go to the channel setting s by pressing on the channel to be set: 4- Set the type of measurement, here we measure the voltage: 5- Choose an adapted caliber for this voltage, in this example: 20V caliber : SEFRAM INSTRUMENTS SAS - 32, rue E.

6- Set the zero’s position, here we will use the “Min” position because we want to visualize a positive voltage. The range will be 0 to 20V: 7- It’s possible to use a filter to remove the glitches, here we will choose 10 Hz: SEFRAM INSTRUMENTS SAS - 32, rue E.

8- Choose the acquisition period, in the example we will use a « 20 ms » sampling period (each channel can have their own sampling period which is different of the sampling frequency of the recorder): 9- The configuration of the first channel is completed and we can visualized the signal: SEFRAM INSTRUMENTS SAS - 32, rue E.

4- Choose the type of measurement, here we measure the temperature with a thermocouple: 5- Setting the type measurement: 1. Choose the thermocouple type, here we will use a K type thermocouple 2. Select the compensation 3. Choose the unit, here we will take the Celsius degree (°) 6- Choose an adapted caliber, in this example we will use a 30°C caliber: SEFRAM INSTRUMENTS SAS - 32, rue E.
