ANALOG/FREQUENCY 5-8 INPUTS
The analog/frequency 5-8 pages are similar to the Analog 1-4 pages. In addition to
measuring voltage signals, Analog/Frequency channels 5-8 are also capable of
measuring pulse based signals. Some examples of pulse based signals are engine
rpm, MAF, vehicle speed, wheels speed, and driveshaft speed. The analog/frequency
channels can also measure signals up to 16.5 volts. The maximum input voltage is
selected by clicking on either 5V or 16.5V in the Calibration Data section. The Input
Mode is user selectable from the following six options; Analog, Frequency, Period, Duty
Cycle, Vehicle Speed, and Engine Speed. Figure 13 below shows Analog/Frequency 5
configured for engine speed.
DIGITAL 1-3 INPUTS
The Switched to Ground Digital 1-3 pages are used to configure the digital ground
inputs. The Channel Options, Live Data, and Sensor Wizard function the same as the
previously discussed analog pages. By default, the digital value is “OFF” when the
input is grounded. If the Invert box is checked, the scaled value will display “ON” when
the input is grounded. Figure 14 below shows Digital 1
configured to read “ON” when
the input is grounded.
