Operating Instruction
WARNING
Do not bring the measurement sensor's
probe into direct contact with the secondary
ignition circuit.
Measuring the frequency of the
high-voltage ignition pulses
The multi-function test lamp is able to meas-
ure the frequency of the high-voltage ignition
pulses. Frequency measurement is activated
by pressing the mode selection button. If the
measurement sensor tip is placed alongside
a spark plug lead (DO NOT TAP IT), the de-
vice is able to measure the high-voltage igni-
tion pulses by means of capacitive coupling.
The frequency value is displayed in Hc (Hz).
WARNING
Do not bring the measurement sensor's
probe into direct contact with the secondary
ignition circuit.

Voltage increase detection
The peak threshold values can be preselect-
ed by briefly pressing the mode selection
button. If the voltage applied at the probe tip
exceeds the threshold
value, an alarm signal sounds.
The threshold value can be set in voltage
steps of 0.5 to 1.0, to 2.0, to 5.0, to 10.0,
to 48.0 V.
