Setting Input Thresholds
Settings for each channel’s high and low temperature thresholds are provided. The connected relay’s normal operating state will toggle (change state) if
these thresholds are met. For both high and low thresholds, the activation and deactivation levels are different to prevent the relay from rapidly toggling
(cycling on and off). Each channel has Hi ON and Hi OFF settings and Lo ON and Lo OFF settings.

Example. This setting can be used to notify if there is an over heated wet exhaust line or if the exhaust line is approaching freezing. If the relay is
Normally On (closed) and Temperature 3 is congured as above, then it will open when the temperature on channel 3 is greater than Temp 3 Hi On
(80°C). To close, the level must drop below Temp3 Hi Off (75°C). Similarly, the relay will open when the temperature is below Temp3 Lo On (4°C,
not shown) and then close again when the temperature is above Temp3 Lo Off (6°C).
To change one of the settings, scroll to desired setting and press Select. Press the LEFT
← or RIGHT → arrow buttons to change the temperature
value and then press Enter to save the setting. Press Cancel to cancel the change.
NOTE: Lower threshold settings cannot be set above higher temperature threshold settings. Similarly, higher temperature thresholds cannot be set
below lower temperature thresholds. The meter will automatically increase or decrease the temperature thresholds to enforce this.
