Performance and
characteristics testing
■ Application example Load interruption test at generator
■ Use pretrigger function to record waveform before and after
interruption
■ Test breaker characteristics
■ Use multiple isolated input channels simultaneously
■ Instantly load paper and print out full-width waveform
■ Application example Commercial power supply line
measurement
■ Use drop trigger to monitor voltage drops
■ Evaluate waveform when switching to UPS or other source
■ Use instantaneous waveform recording for 50/60 Hz
■ Isolated inputs eliminate short-circuiting risks
■ Application example Railway carriage problem analysis
■ Use pretrigger function to record instantaneous waveform
before and after problem
■ Check notch curves and cam progression waveform
■ Use logic probe to record cam contact point signal waveform
■ Record MG startup current waveform using clamp sensor
■ Application example Motor startup current measurement
■ Observe correlation between main motor current waveform
and relay signal
■ Record up to 3 m 20 s at 1/1000 s (1 ms per division)
■ Make simultaneous current and voltage measurements using
multiple channels and isolated inputs
■ Use trigger wait function to pinpoint and record problem
waveforms only
■ Application example Measurement of hydraulic machinery
operation waveform
■ Perform braking mechanism measurement
■ Perform X-Y measurement of valve fl ow and pressure
■ Perform X-Y measurement of load and displacement
■ Use pen up/down and playback functions
■ Application example Check for bearing wear and
deterioration
■ Perform FFT analysis over a frequency range from DC to 8
MHz
■ Perform long-term signal recording and analyze only
required parts
■ Use FFT analysis to diagnose cracks and similar problems
Note: FFT analysis function available from version 2.00 onward
