NOTE
: When UltraGauge is powered down, pressing the button on the Blue Adapter will wake the Adapter.
However, if the “power off detect” mode remains satisfied, UltraGauge will quickly reenter low power mode.
NOTE:
The “Power on detect” mode setting is ignored and set to Monitor Battery Voltage mode when the “Power
off detect” mode is set to mode 5.
Bat High Threshold
This setting is used in conjunction with the Monitor Battery Voltage “Power on Detect” . This setting is ignored for
the other “Power on Detect” modes. By default the voltage threshold is set to 13.2 volts and for most vehicles, this
is the best setting. However, if when the vehicle is started, UltraGauge does not wake; decrease the threshold in
0.1 volt steps until UltraGauge wakes consistently. If UltraGauge falsely wakes when the engine is not running,
increase the threshold in 0.1 volt steps until UltraGauge no longer falsely wakes.
Battery Drain
This discussion generally applies to newer vehicles which use the CAN protocol or vehicles with electrical system
issues. When the ignition is switched from RUN to OFF, the vehicle’s electrical system modules stay active
drawing battery power for several minutes. Over time, various systems enter lower power modes and the drain on
the battery decreases. However, UltraGauge can cause these systems to not enter low power mode. Normally, once
the Adapter has detected ignition off, the Adapter will enter a low power mode and wait for the vehicle’s systems to
become active at the next ignition on. However, since the vehicle’s electrical systems do not shut down;

Adapter quickly attempts to establish communication again. This communication in turn causes
the vehicle’s systems to remain on indefinitely and results in battery drain. Monitor Battery Voltage mode resolves
this issue.

Power off Detect mode
For most vehicles UltraGauge will correctly detect when the ignition has been switched to OFF with the default
setting. Should UltraGauge remain on beyond 15 seconds after exiting the vehicle, use this setting to change the
method UltraGauge uses to detect that the ignition is in the OFF position.
Read OBDII Sensor (default)
OBDII PID 00 sensor is read. If the vehicle’s computer does not respond with the requested parameter after
“Power off retries” attempts, the ignition is assumed OFF.
Monitor RPM
Whenever the vehicle’s ECU returns a value of RPM less than 512 for “Power off retries” consecutive times,
the ignition is considered to be in the OFF position.
Monitor Battery Voltage
When the engine is running, the alternator causes the battery voltage to exceed 13.2V. When the engine is not
