Select The Proper Hardware Filter; Choose An Appropriate Sampling Rate; Select The Proper Location; Use The Correct Wiring - VTI Instruments EX1000A User Manual

Select the proper hardware filter

Unless the bandwidth of the sensor requires a higher instrument bandwidth, the 4 Hz setting of the
EX10xxA hardware filter should be used, as it provides the greatest immunity to external electrical
and magnetic interference.

Choose an appropriate sampling rate

For best instrument noise performance, the sampling rate should be set as low as the data collection
requirements allow. For more details, see Sampling Rate / Noise Performance in Section 3.

Select the proper location

The EX10xxA unit should be located away from sources of high or low temperature, strong air
currents, and high magnetic fields. For more details, see Installation in Section 2

Use the correct wiring

Best results will be achieved with the shortest and largest thermocouple wire that the physical
requirements of the application can support. In addition, shielded thermocouples can be employed
to raise the system's rejection of electrical interference. For more details, see Input Connections /
Wiring in Section 2.
