ISSPRO 5" Programmable Tachometer

Microprocessor Aircore Version

General Information:

Operating Voltage: 11-16VDC (24 VDC versions available)

Input Signal: Gear tooth sensor, AC generator, alternator tap

Programmable Range: 1-255 pulses per engine revolution (gear teeth, magnets, etc.)

Transient Protection: +100 V, -400 V

Reverse Voltage Protected

Hourmeter (optional) operates only when engine runs

Calibration:

Remove the calibration switch cover. Each of the first eight switches has a

different value as shown in the table on the right. Add the switch values to

equal the number of pulses per engine revolution. These switches will be

set “on” (up.) All others will be off.

Important: Switches 9 and 10 are always off.

Note: Power must be cycled when changing switch settings. If power is

left “On”, changing the switch will have no effect on calibration until power

is interrupted.

Example: Find switch numbers by subtracting the switch value from the remaining number. Always use the

largest value that can be subtracted from the remainder of

each successive step. For gear with 103 teeth:

Or use the calibration chart provide on pages 3 and 4.

Signal Generator (Sender unit): Generator is installed

on tachometer cable drive of engine:

#Pulses/Rev = (# sender pulses/turn) X (ratio of takeoff rpm to engine rpm)

If the number of pulses per revolution (from equation) is not a whole number the tach will not be accurate. In this

case, select a generator so that this number is non-fractional.

Example: # sender pulses per turn = 15, takeoff ratio = 0.5:1 (i.e. cam drive);

# Pulses / Rev = 15 X 0.5 = 7.5. This will result in an error in the tachometer reading. Select a sender with an

even number of pulses per turn (e.g. ISSPRO R8970). The # pulses per revolution will then be a whole number, in

this case 15.
