Page 19: Setup And Precautions
Setup and Precautions 3.1 Power The recorders work on normalized mains (See chapter Technical specifications). They are designed for indoor use. MAINS CONNECTION These instruments must be connected to the mains with the provided cord. SECURITY These instruments are security class I according to the classification CEI1010 (NF EN 61010) Security rules for electrical appliances for measurement, regulation and laboratory.
Page 20: Connection To The Measurement Networks
Setup and Precautions If the configuration has changed at the power-up, contact the after-sales service. If the initial configuration is wrong, you can start with the default configuration: You must then press several times the top right of the appliance at the start-up until the homepage shows up (at the place of the main Menu key under normal conditions).
Page 21: Gauge Strain Measurement
Setup and Precautions Do not use male banana plugs for welding: the soldered joint would alter the thermocouple effect. Non-isolated differential input module and Isolated strain gauge input module: The voltage produced by the thermocouple effect must be measured between the « + » and « - » poles of the inputs with wires on the screw terminal. To guarantee the right measurement, plug directly both ends of the thermocouple cord on to the input you want with respect for the polarity.

Page 23: Earth
Setup and Precautions 3.4.7 Earth For measuring very low voltage values, the problem of the parasite voltages induced by electromagnetic fields or ordinary mode voltages are all the more important than the selected sensitivity is high. Hence, it is important that the outer cables are correctly settled.
Page 24: Calibration Of The Offsets
Setup and Precautions 3.6 Calibration of the offsets You can easily calibrate the inputs of the recorder for the offsets of voltages and thermocouples. This will remove any offsets present on different channels. To do so: 1. Let the appliance work for 20 minutes (ambient temperature between 20 and 25 °C). 2.
