Recording Intermittent Leakage, Engine Performance and Relay Timing
-Application Examples-
Unpredictable intermittent leakage is monitored unattended by recording instantaneous waveforms of the leakage current and line voltage
Leak current (CH1)
Line voltage (CH2)
Trigger point
Recording of leakage is
triggered when the input
exceeds preset upper or
lower limits.
Every time a leakage phenomenon
occurs, the waveforms can be
printed out or the data saved on an
ATA card.
Data saved on a flash ATA card
can be read back by the 8807
-01
for analysis of peak current values
at breaker trip time using the
cursor function.

Allows the balance between boost, oil pressure, air fuel
ratio, ignition timing, engine speed, injector aperture,
etc., to be observed and recorded as waveforms.

Circuit breaker cut-off in a power circuit can be
investigated by analyzing the relationship of multi-
point logic signals to the analog waveform. Up to eight
channels are provided for recording relay operation
using logic probes.
Use the model 9320-01 for non-voltage contact signals,
and the LOGIC PROBE 9321-01 with isolated inputs
for powered AC relay signals.
Motor power-on inrush current waveforms
can be precisely recorded. The CLAMP ON
PROBE
s model 9018-10 and 9132-10 are
available for current measurement, as is the
CLAMP ON LEAK HiTESTER
3283.
In addition, to measure direct current waveforms,
a variety of sensors such as the
UNIVERSAL
CLAMP ON CT
s model 9277, 9278 and 9279
are available upon request.
Recording of motor rush current
Abnormal halts and warnings issued by sequence
control devices in manufacturing production and
testing lines can be caused by AC power hits or
low voltage. Such anomalous behavior can best be
analyzed by setting the sequence relay signal as a
trigger to record the abnormal AC power waveforms
and DC voltage systems.
Analysis of Sequence Control Device Faults
For long-term monitoring, use the AC ADAPTER 9418-15 for the MEMORY
HiCORDER
8807-01 and the AC ADAPTER 9445-02/-03 for the CLAMP
ON LEAK HiTESTER
