    Safety Warnings In installation and use of this product, comply with the National Electrical Code and any other applicable Federal, State, or local safety codes. The NH sensor is heated, gets hot, and can burn you. Always wear eye protection when working near engines, vehicles, or machinery. During installation, turn off the power and take all other necessary precautions to prevent injury, property loss, and equipment damage.

  • Page 15: Mounting The Nh 3 Sensor

    Mounting the NH Sensor Sensor   Thread is 18mm x 1.5mm  Mount downstream of the SCR (Selective Catalytic Reduction) catalyst or where there are not significant amounts of CO (carbon monoxide). This is due to the sensor’s cross-sensitivity to CO. To avoid reversion effects, mount at least ten exhaust diameters upstream of exhaust end.

  • Page 16: Front Panel And The "Sys" Key

    Front Panel and the “SYS” Key The NH 5250 display head can be thought of as two single-channel display heads in one package. One NH module can be assigned (via the Mod Setup Option) to the upper display, upper four leds, and analog outputs 1, 2, 3 (i.e. the upper channel) and a second NH module can be assigned to the lower display, lower four leds, and analog outputs 4, 5, 6 (i.e.
