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

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

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".

Measurement Start

Make sure the power recorder's connecting cord is connected to the power terminal of the

power source.

Press the [START] key to start the measurement. When the trigger activates, the

instantaneous stop waveform appears on the waveform display screen. After the waveform

equal to the recording length is captured, the state returns to "wait for trigger" again.

To stop the measurement, press the [STOP] key. After the measurement stops, the voltage

see page 16.

Trigger activates when

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".
