Commercial Tiny-Tach™ — Operating Instructions
Operation
When engine is started, the unit will automatically switch to the
Tach Mode and display an RPM reading. (figure
3)
The unit has internal power to maintain all of its stored data. When the external power is turned
off, the unit will go into low power mode and the display will shut off. If the menu button is
pressed in the OFF state, the unit will turn itself back on using
internal battery power. It will
start in the TOTAL RUN TIME mode. When the menu button has not been
pressed for approximately
30 seconds, the unit will turn itself off to conserve battery power. Excessive use of this feature
will limit battery life. However normal use will not have any appreciable effect on battery
life.

In general, when displaying time, if the number has a colon on, then
the number represents hours and minutes, otherwise it represents
just hours.
Menu Button
This single button allows the user to scroll through all of the various display
modes and also allows setting/resetting of parameters. Each mode will be explained in detail
in the following sections.
In general, each time the button is pressed, a new mode is displayed. If the button is pressed
and held down for 5 seconds, the Reset Icon will appear, indicating that the unit will reset this
parameter if the button is released while the ICON is on. If the
button is held for 10 seconds,
for some parameters the RESET Icon will change to a
SET icon. If you release the button with the
SET icon on, you will go into SET
mode as explained below. If you continue to hold the Set Icon
will disappear and no parameter change will occur.
If one wishes to just view the parameters, press the menu button until the parameter icon at the
top of the display changes and release. Continue to do this until the parameter desired is indicated
on the display. This parameter will remain on the display for 30 seconds and then will go back
to its original mode.
If one wishes to reset a particular parameter, do the following. Press the menu button and the
parameter icon will cycle to the next mode. If this is not the parameter you wish to reset, release
the menu button and press again to go to the next parameter. If this is the parameter you wish
to reset, hold the menu button for 5 seconds. The RESET icon will appear.
Release the menu button
and the parameter will be reset. Several examples will be given in the next sections.
Total Run Time Mode
As stated earlier this mode is displayed when external power is on. (The motor is not running)
This mode is also displayed when
the unit is first turned on. When a user is cycling through all of the modes, and goes past
the last one, the unit starts over at this one.
If power is on and the unit is already in the TOTAL
RUN TIME mode,
cycle through all the other modes by pressing and releasing
the menu button.
Job Time Mode
This timer is typically used to measure the time of a particular work
job. If user wishes to time
how many run hours it takes to do a job, then the user can reset this
timer at the start of the job, and the unit will keep track of the
run hours in this display. To display JOB TIME, press and release the
menu button, until the Job Icon is displayed. (figure 5)
To reset JOB TIME, press and release
the menu button until you get to the TOT display.
TIME. Then press and
hold the menu button. The JOB TIME will
appear. Continue to hold the menu button until the RESET icon
appears. Then release the menu button and the JOB
TIME is reset.

Service Timers
The unit contains two count down service timers. They can be used for example, for Oil change
and Air filter replacement. To give an example, say that service timer 2 is set 250 hours. As
the Engine runs, the timer will count down to zero. At this point, the display will flash the
SVC2 icon until the timer is reset back. When the timer is
reset, it goes back to its initial
time, in this example, 250 hours. This time is changeable by "Setting"
the initial service time. If a user does not wish to use one or both of the service timers, they
can be disabled by setting them to 0 service time.
To display service timer one, press and release the menu button until
the display shows SVC. (figure 8) Pressing
and releasing the menu button one more time will display service
timer two. (figure 9)

Service Timer two |
To reset a service timer, the procedure is just like resetting any
other timer. Press and release the menu button to get to the timer
you wish to reset. When the icon for that service timer is displayed
(either SVC or SVC2),
do not release the menu button. Continue to hold the button until
the RESET Icon appears. When this
happens the number displayed will be the reset value that was
previously set. This value could be zero if the timer was disabled.
If this value is acceptable, release the button and the display
will show the new service time left. (figures
10 through 12)

If the reset value of the service timer needs to be changed, then
do not release the menu button when the RESET Icon
is displayed. Continue to hold it until the SET Icon
is displayed and then release. The SVC and
SET icon
will both remain on with the current value of the starting
value of service timer displayed. In this mode, every time you press
and release the menu button the starting value of the service counter
will increment by 5 hours up to a maximum of 250 hours and
then wrap around to zero. To set this value to the current one displayed,
just wait for 15 seconds and the unit will go out of set mode
and display the current service time. (figures
13 through 17)

Service timer one (SVC) and service timer two
(SCV2) operate identically. When
service timer one expires, you get a SVC icon flashing.
When service timer two expires, you get
a SVC2 icon flashing. To disable one or both of the service
timers, just set its start value to
zero.
Maximum RPM
The unit also keeps track of the maximum RPM the motor has run at.
This can be displayed by pressing
and releasing the menu button until the MAX icon appears. (See figure 18)
To reset the maximum RPM, the procedure
is just like resetting any other parameter. Press and release the
menu button until to get to the MAX icon.
Hold the menu button until the RESET icon
appears. Release the button and the maximum RPM parameter
is reset.

Battery Lifetime
The microprocessor and display are powered by an Internal lithium battery totally independent
of the external amplifier power source, so run time hours will not be lost if the external source
is disconnected. This battery is not replaceable but should last more that five years.
Note:
when external power is applied, the Lithium battery is charging.
Pulse per number of degrees rotation
Hold the SELECT button down when
selecting the degree setting and the SET icon
will be displayed.
(figure 21) Next push the SELECT button
again until the number of
degrees/pulse is selected. STOP and wait. The Tach will go to TOTAL
or turn off. (figure 22)
