Section 1: The Spark Analyzer
1-1 Introduction
The Spark Analyzer is used to measure secondary ignition firing events.
Because firing voltages are typically in the thousands, voltage readings
are referred to as Kv (Kilovolts) readings. Peak firing and burn voltages
are both measured by this unit. The tester will also measure the length of
burn time. This is referred to as ms (milliseconds). All of the measure-
ments are possible on ignition system using distributors and on DIS
(Distributoriess or Direct Ignition System) type system. Measurements
are not possible on coil on plug systems.
Much like more costly ignition oscilloscopes, the Spark Analyzer allows
the user to compare ignition firing events to one another. These readings
may be taken at idle or at higher engine speeds with the engine under
load. The Kal Equip Spark Analyzer will often test an ignition system in
less time than required to hookup an ignition oscilloscope.

ON/OFF Button:
* Button:
This button is used to view the triple screen. The triple screen gives all
three real time readings at one time.
RESET Button:
The Reset button clears the minimum and maximum values. All min. and
max. values will be cleared whether they are currently being displayed or
not.
NOTE: The RESET button does not function while the unit is in Triple
Screen mode.
P - Peak Kv:
Pressing the P button will display Peak Kv readings. The "real time',
minimum, and maximum
readings will all be displayed. Peak Kv is the
secondary ignition voltage it took to initiate the spark event.
B - Burn Kv:
Pressing the B button will display Burn Kv readings.
The "real time',
minimum, and maximum
readings will all be displayed. Burn Kv is the
secondary ignition voltage it took to maintain spark during the combustion
process.
T - Burn Time ms:
Pressing the T button will display Burn Time readings. The "real time",
minimum, and maximum
readings will all be displayed, Burn time is the
length of time from Peak Kv until Burn Kv ends (length of spark event). The
Burn time is measured in milliseconds (one thousandths of a second).
Pickup Clamp (blue):
The Pickup Clamp connects the tester to the vehicle's spark plug wires for
firing event measurements.
Display:
The display is 16 characters by 2 lines and will be used to show readings
and display information.
Ground Clamp (black):
The ground clamp is used to supply ground for the Pickup Clamp's
harness shield, If this is not properly grounded misleading data may be
received.
Battery Compartment:
The battery compartment located on the back of the tester, is used to hold
the units 9V battery.
