POWER HiCORDER

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.

Measurement Start
Make sure the power recorder's connecting cord is connected to the power terminal of the
power source. Then, press the [START] key to start the measurement. A voltage waveform
appears on the waveform display screen.
To stop the measurement, press the [STOP] key. After the measurement stops, the voltage
waveform last captured appears on the screen.
When multiple waveforms are captured, they are displayed in the
f
ollowing way according to the sequential save.
To display the waveforms, press the channel select key (CH1). The
displayed number indicates the block in the diagram which appears
in reverse color. This block is the waveform currently displayed on
the waveform display screen.
To change the display, move the flashing cursor to the number's
position or directly to the block's position ( ), then press the /
key to confirm.
If you start the measurement again, the previous waveform is
discarded and recordin
g
starts from the first block.
To view the voltage waveform, set the measurement mode to "Waveform". For the time axis
setting, "2ms" would be quite satisfactory. Set the recording length to "20 DIV".
In the case of voltage waveform, after selecting "Volt" as the input mode, set the range to
"200V Line".

the effective level drops
below 190 Vrms.
To record the instantaneous stop waveform of the power source, set the measurement mode to
"Waveform". For the time axis setting, "2ms" would be quite satisfactory. Set the recording
length to "20 DIV".
In the case of voltage waveform, after selecting "Volt" as the input mode, set the range to
"200V Line". If you set the range to "200V Line", then you can measure the 220V and the 240V
power voltages.
Set the trigger to "DROP". For the measurement frequency, specify one which is suitable for the
region you are located. For the level, set a RMS value so that when the effective power voltage
drops below this value, the trigger will activate. In this example, it is set to "190.0Vr".
To see the waveform before the trigger point, try to set the trigger to "50%". Until the trigger
activates, the state remains as "wait for trigger".
