Measurement categories (Overvoltage categories)

This instrument complies with CAT II safety requirements. To ensure safe operation of measurement instruments, IEC61010 establishes safety standards for various electrical environments, categorized as CAT I to CAT IV, and called measurement categories. These are defined as follows.

CAT l

Secondary electrical circuits connected to an AC electrical outlet through a transformer or similar device.

CAT ll

CAT lll

CAT lV

Primary electrical circuits in equipment connected to an AC electrical outlet by a power cord (portable tools, household appliances, etc.)

Primary electrical circuits of heavy equipment (fixed installations) connected directly to the distribution panel, and feeders from the distribution panel to outlets.

The circuit from the service drop to the service entrance, and to the power meter and primary overcurrent protection device (distribution panel).

Higher-numbered categories correspond to electrical environments with greater momentary energy. So a measurement device designed for CAT III environments can endure greater momentary energy than a device designed for CAT II. Using a measurement instrument in an environment designated with a higher-numbered category than that for which the instrument is rated could result in a severe accident, and must be carefully avoided. Never use a CAT I measuring instrument in CAT II, III, or IV environments. The measurement categories comply with the Overvoltage Categories of the IEC60664 Standards.

Accuracy

We define measurement tolerances in terms of f.s. (full scale), rdg. (reading) and dgt. (digit) values, with the following meanings:

f.s.

(maximum display value or scale length) The maximum displayable value or the full length of the scale. This is usually the maximum value of the currently selected range.

rdg.

(reading or displayed value) The value currently being measured and indicated on the measuring instrument.

dgt.

(resolution) The smallest displayable unit on a digital measuring instrument, i.e., the input value that causes the digital display to show a "1".

2.5 Connecting the 9322 DIFFERENTIAL PROBE

When using grabber clips, the 9322's maximum rated

DANGE

WARNING

voltage to earth is 1500 V AC or DC (CAT ll) / 600 V AC or DC (CAT lll); when using alligator clips, it is 1000 V AC or DC (CAT ll) / 600 V AC or DC (CAT lll). To avoid electrical shock and possible damage to the instrument, never apply voltage greater than these limits between the input channel terminals and chassis, or across the input of two 9322s.

Maximum input voltage is 1000 VAC/2000 VDC (CAT ll) / 600 V AC or DC (CAT lll). Do not measure voltage in excess of these limitations, as doing so may danger the instrument or cause an accident that might result in injury or death.

9322 input part is applied with high voltage. To avoid electric accident, be sure to turn off the power of equipment to be measured before connecting. After connection is properly handled, turn the power on.

Before using the instrument, make sure that the insulation on the probes is undamaged and that no bare conductors are improperly exposed. Using the instrument in such conditions could cause an electric shock, so contact your dealer or Hioki representative for repair.

9322 is a differential probe that connects to analog input. After high voltage is input to H and L terminal and divided by 1/1000, the difference is output as signal to GND.

secondary side of a breaker, so the breaker can prevent an accident if a short circuit occurs. Connections should never be made to the primary side of a breaker, because unrestricted current flow could cause a serious accident if a short circuit occurs. To avoid short circuits and accidents that could result in injury or death, use clamp testers only with power lines carrying 600 V rms or less.

The 8715-01 is fundamentally a voltage measuring device. Although it does not measure current directly, current measurement is possible using the voltage output of a clamp sensor.

Care of recording paper

While unopened, thermal paper will not be affected by the environment, provided that ambient temperature and humidity do not exceed normal levels. For long-term storage, temperature should be lower than 40 Low temperatures cause no problem.

After opening, protect the paper from strong light, to prevent discoloration.

Storing data

As the recording paper is thermally sensitive, be aware of the following points: ･ To avoid paper discoloration, do not expose it to direct

sunlight, and store at no more than 40

･ For permanent storage of important recorded data,

photocopy the recording paper.

･ If the thermal paper is exposed to an organic solvent such

as alcohol or ketone, it may no longer develop properly, and recorded data may fade.

･ Also, the thermal recording paper is ruined by contact

Waveform Measurement Mode

3.1 Outline of the Waveform Measurement Mode

The Waveform Measurement Mode provides a variety of settable triggers that can be used to easily record waveform anomalities associated with high-speed transient phenomena such as instantaneous power dropouts and brownouts. Features of the Waveform Measurement Mode are as follows.

(1) Measures instantaneous commercial mains power

waveforms ･ Measures instantaneous, impulse and overvoltage

mains voltage waveforms

･ Measures peak load current when used with a clamp

sensor

(2) Powerful waveform judgment triggers

･ Judges waveforms in real time at 125-μsintervals ･ 2.5-μs sampling interval allows measuring nearly

instantaneous impulses

(3) Voltage-drop trigger effectively detects momentary

power dropouts ･ Detect momentary dropouts as small as one-half

cycle, or optionally set voltage drop detection according to effective value (rms) level.

______________________________________________________________

3.1 Outline of the Waveform Measurement Mode

The Number of Waveform

The number of waveform anomalities that can be sequentially recorded (the sequence limit) depends on the selected recording length. When the number of sequentially recorded waveforms has reached the sequence limit, the earliest recorded waveform is overwritten. Refer to 3.3.3 "Setting the Recording Length" for sequential recording setup, and 3.8 "Sequential Save Function" for the display procedure for sequentially saved waveforms.

control range

For purposes of creating a control range for a standard waveform (either a sine wave or the previous cycle), one cycle period is considered to begin at the positive-going 0volt crossing (positive 0 crossing).

(1) Sine Wave

The control range is based on a sine wave (with RMS value voltage) at the mains frequency.

(2) Previous Cycle

The control range of each cycle is based on the previous cycle of the input waveform. This selection is used when gradual changes should not cause t riggering.

Recording Length and Sequential Save

The maximum number of events that can be sequentially recorded (the sequence limit) depends on the recording length set for each event. For sequential save operation, the internal memory is partitioned for storing multiple sets of data. When the number of waveforms acquired reaches the sequence limit, no more waveforms will be acquired in response to further trigger events. Refer to Section "6.4.2 Sequential Save Function" for the details.
