CONTROL FUNCTIONS

Interweaves (alternates rpm with next test measurement).

Control

Displays minimum value detected for next test.

Control

Displays maximum value detected for next test.

Control

Displays peak-to-peak value for next test.

Control

Interweaves two tests.

ENGINE TESTS

Measures average speed of engine crankshaft by means

ENGINE RPM

of pulse tachometer.

Measures engine's power producing potential in units of

POWER TEST (RPM/SEC)

rpm/second.

Evaluates relative cylinder compression and displays

COMPRESSION UNBALANCE

percentage difference between highest and lowest values

in one engine cycle.

FUEL SYSTEM TESTS

24*

Measures fuel pump outlet pressure.

FUEL SUPPLY PRESSURE

Detects clogging by opening a differential pressure switch

FUEL FILTER PRESSURE

across secondary fuel filter.

DROP

STARTING/CHARGING SYSTEMS TESTS

Measures battery voltage at or near battery terminals.

BATTERY VOLTAGE

Measures voltage present at starter motor positive terminal.

STARTER MOTOR VOLTAGE

Measures voltage drop on starter ground path. High

STARTER NEGATIVE CABLE

voltage drop indicates ground path resistance.

VOLTAGE DROP

Measures voltage present at starter solenoid positive

STARTER SOLENOID

VOLTAGE

terminal. Measures current through battery ground path

shunt.

Measures average current to or from starter.

71*

STARTER CURRENT

AVERAGE

Tests condition of starting circuit and ability of starter to

72*

STARTER CURRENT FIRST

deliver sufficient starting current.

PEAK

Evaluates battery condition by measuring voltage and

BATTERY INTERNAL

73*

current simultaneously.

RESISTANCE

Measures combined starter circuit and battery internal

74*

STARTER CIRCUIT

resistance.

RESISTANCE

Measures rate of change of battery resistance to provide

75*

BATTERY INTERNAL

indication of battery condition.

RESISTANCE CHANGE
