General Wiring Recommendations

Keep the following recommendations in mind when wiring signals to a DT9828 module:
• Separate power and signal lines by using physically different wiring paths or conduits.
• To avoid noise, do not locate the instrument and cabling next to sources that produce high
electromagnetic fields, such as large electric motors, power lines, solenoids, and electric
arcs, unless the signals are enclosed in a mumetal shield.
• Locate the DT9828 module as far away as possible from sources of high or low
temperatures or strong air currents, such as fans.
• Prevent electrostatic discharge to the I/O while the instrument is operational.
• When wiring thermocouples, use a wire insulation strip length of 0.197 inches
(5 mm).
• Use 16 AWG to 26 AWG shielded wire for maximum rejection of electrical interference.
Note: The DT9828 module requires a warm-up time of 10 minutes for the analog circuitry to
stabilize.
