MAN 650067:F

(Auto Cal continued)
NOTES: You do not have to drive at a constant speed nor do you have to avoid stopping
during Auto Cal. When completed, you do no need to stop, you may, but you can also
just press and release SW1 as you pass the 1 mile mark.
The message display cannot be used to determine when the mile has been driven, it’s
only there as a reference to indicate pulses are coming into the control box. Even if you
have an 8000 PPM sensor you may calibrate at 9xxx PPM (for example) due to gearing
and tire size.
Also be aware that the odometer miles are calculated from the speedometer cal value; if
it is not calibrated properly, the odometer miles could be higher/lower than actual.
***If you do not receive more than 2000 pulses during calibration the unit will error out.
Adjust Mode (ADJUST)
A
djust is different depending on what input signal is selected in the SENDER menu.
• When “ADJUST” is displayed, press and hold SW1 until you get “ - ” then release the switch.
• Now select the primary units by pressing and releasing SW1, “MPH” for miles per hour or
“KMH” for kilometers per hour.
• When the desired units are selected, press and hold SW1 until you see the “ - ” then release
SW1.
If “NOMAL” is selected for the sender type it will allow you to adjust the signal that is being
supplied to the SPD SND terminal coming from a pulse generator or ECU. The fuel, volt, oil,
water, and tach will operate normally. The speedometer will show the speed reading and the
speed message display will say “ADJUST”. Begin driving at a known speed. Press and hold
SW1 to increase the speedometer reading; the next press and hold of SW1 will decrease the
speedometer reading. You can continue adjusting up and down as needed until the reading is
correct. When the speedometer is correct, stop and restart the system, by turning the key/power
off and then starting the vehicle back up. The new calibration will be saved when the power is
shut off.
If “BUS” is selected for the sender type, the speed signal
should be coming into the AUX
I/O port through the use of a future BIM module. The adjustment ratio ranges from 75 – 125%
on this setting as it is assumed that the signal from the external device is the correct pulse rate;
there are only provisions for slight adjustment. The odometer will light up and show “CL xx” xx
is adjustable from 75 – 125 and is the percentage the input is corrected by. If set to 100 the
signal is uncorrected and whatever the BIM module is reading is displayed on the dash.
NOTES: For Adjust mode you can follow another vehicle, time yourself, or use a GPS as
a reference. A chassis dyno is another excellent way to use the Adjust mode.
Also be aware that the odometer miles are calculated from the speedometer cal value, if
calibrated properly, odometer miles could be higher/lower.
Service countdown meter (S-SET)
The service countdown meter or, S-SET, allows you to set a mileage value that will
decrease as the odometer miles increase. When the value gets to zero, a message “S DUE” will
appear on the message display on power up to remind you that service is due. This can be
used for routine maintenance reminders such as oil changes.
• When “S-SET” is displayed, press and hold SW1 until you get “ - ” then release the switch.
T
he current service setting will be displayed.
• Press and release SW1 to increase the value from “OFF” then “500”-“7500” in 500 mile
increments.
• Once the desired setting is displayed, press and hold SW1 until “ - ” “DONE” is displayed to
save the value.
