Introduction
The 8715-01 POWER HiCORDER measurement guide describes some several measurement
examples. Therefore, the settings may be different from those used in the actual measurements
you perform. In this case, refer to the POWER HiCORDER's instruction manual and modify the
appropriate settings accordingly before performing your measurements.
Also, be sure to read the POWER HiCORDER's instruction manual for information on cautions
to take when connecting the device and performing measurements. Make sure you fully
understand the contents before operating the device. HIOKI cannot be held liable for any
accidents except for those caused by the product.
The following table of contents lists the several different measurement examples as well as
their reference page numbers. All these examples assume only CH 1 is used in the
measurements. Therefore, turn off the waveform display of all other channels. Also,
measurement examples described in this measurement guide assume all other settings use the
factory defaults. No attempt is made to describe settings not directly related to the
measurements. For the information, refer to the 8715-01 POWER HiCORDER's instruction
manual.

Waveform Detection Trigger
The waveform detection trigger function compares the measured signal with a pre-defined control
waveform range, and triggers if the signal deviates from the control range voltage. The control
range consists of a positive and negative amplitude offset from either a standard sine wave or the
previous input cycle.
The settable standard voltage and control range are limited by the voltage range setting.
For the waveform (whether it is a sine wave or a previous waveform) functioning as the reference
waveform used in creating the control range, it is a cycle of waveform starting where the cycle
begins from the time 0V is raised and then cut horizontally (raise 0 close).
(1) Sine Wave
The control range is based on a sine wave (with RMS value voltage) at the mains frequency.
(2) Previous Cycle
Set the control range to the waveform of the input waveform in the previous cycle and then
compare it with the input waveform. Use it if you do not want to set up a trigger for the warped
portion when measuring the waveform of the warped power source.
Control range for printing
If the reference waveform used for creating the control range is a sine wave (50/60 Hz), when the
waveform judgement trigger activates and printout results, one cycle of the control range (gray
part) is also printed at the same time as the abnormal waveform.
This is useful when you want to find out how much the deviation from the control range is.

Starting the measurement
Press the [START] key to start the RMS Trend recording
of the power variation. While recording, the trigger
activates when the RMS value drops by 190V.
Because the instantaneous waveform recording length is
set to "20 DIV", when the trigger activates, the waveform
data equal to "20 DIV" is captured, starting from the
trigger point.
If the recording length is 20 DIV, 16 phenomena of
instantaneous waveform data can be captured.
If there are more than 16 phenomena, then data cannot
be captured even if the trigger activates.
During the instantaneous waveform recording in the power variation mode, transient phenomenon
which occurs during the actual value recording of the power variation (voltage or current) can be
recorded at high speed using the waveform level.
In the Basic Setting screen of the RMS Trend Measurement mode, if the instantaneous
waveform recording (Memory Record) is set to "ON", the time axis and recording length settings
become available. The recording length (recording time) determines the number of
instantaneous waveforms to capture.
In this example, the time is set to "2ms" and recording length to "20 DIV". The input setting is
set to "Volt", the input range to "200V Line", and the display position to "Std".
When the instantaneous waveform recording is ON, the instantaneous waveform trigger can be
set at the CH SETTING screen. In this example, the RMS level trigger is used. The trigger
activates when the voltage drops below the voltage set; and the instantaneous waveform is
captured. The RMS value level is set to "190.0 Vr", and the slope to " : falling edge".

In this example, the 220 V line's voltage waveform, current waveform, and leak current waveform
are monitored simultaneously; when abnormal situation arises they are measured at the same
time. This example uses CH1 to measure the voltage waveform, CH2 the current waveform and
CH3 the leak current waveform.

The pre-trigger function serves to record the waveform not only after but also before triggering has
occurred.
In the Waveform measurement mode, using the recording start point as 0% and the recording end
point as 100%, the trigger point can be specified in percent. When all trigger sources are set to
OFF, the pre-trigger setting is invalid.
・In Waveform measurement mode, when the pre-trigger is set, the trigger will not be registered
for a certain period after the start of measurement. (During this interval, Pre-trig wait is shown
on the Waveform display screen.)
・When the trigger can be registered, the indication Wait for trig is shown on the waveform display
screen.
If the recording length is 20DIV, pre-trigger 10% = 2 DIV and pre-trigger 50% = 10 DIV.
