Measurement categories (Overvoltage categories)

This instrument complies with CAT II safety requirements. To ensure safe operation of measurement instruments, IEC 61010 establishes safety standards for various electrical environments, categorized as CAT I to CAT IV, and called measurement categories. These are defined as follows.

CAT I

CAT II

CAT III

CAT IV

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

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

Handling the CD

CAUTION

Always hold the disc by the edges, so as not to make fingerprints on the disc or scratch the printing. Never touch the recorded side of the disc. Do not place the disc directly on anything hard. Do not wet the disc with volatile alcohol or water, as there is a possibility of the label printing disappearing. To write on the disc label surface, use a spirit-based felt pen. Do not use a ball-point pen or hard-tipped pen, because there is a danger of scratching the surface and corrupting the data. Do not use adhesive labels. Do not expose the disc directly to the sun's rays, or keep it in conditions of high temperature or humidity, as there is a danger of warping, with consequent loss of data. To remove dirt, dust, or fingerprints from the disc, wipe with a dry cloth, or use a CD cleaner. Always wipe radially from the inside to the outside, and do no wipe with circular movements. Never use abrasives or solvent cleaners. Hioki shall not be held liable for any problems with a computer system that arises from the use of this CD, or for any problem related to the purchase of a Hioki product.

2.8.2 Care of Recording Paper

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

The recording paper uses a thermochemical reaction. Note the following points:

To avoid discoloration, do not leave recording paper in direct sunlight. Store at not more than 40 (104 ) and 90% RH. To keep definitive data, make photocopies of the recordings. Thermal paper will blacken when brought into contact with alcohol, ester, ketone, or other volatile organic substances. If the thermal paper absorbs an organic solvent such as alcohols or ketones it may no longer develop properly, and recorded information may fade. Soft PVC film and transparent contact adhesive tape contain such solvents, so avoid using them with recordings. Avoid interleaving the thermal r ecordings with damp diazo copies.

Numerical Calculation with New Data

NOTE

From the Waveform Screen, press the

START

button to begin measurement. Data input begins when trigger conditions are met. After the specified data record amount is input, numerical calculation starts, and when calculation is finished the results are displayed. If printing or saving of calculation results has been enabled, those processes execute. When starting to input subsequent data, the previous data is cleared.

The calculation area can be specified by the A/B cursors. If only cursor A is used, the calculation area extends from the cursor to the end of the measurement data. The (horizontal) line cursor is not used to specify calculation area. When both numerical calculation and sequential save are enabled at the same time, calculation starts after sequential save finishes. All blocks are processed by the calculation, so the calculation result is refreshed and the final calculation result is that of the last block. To view the results of all calculations, enable printing or saving of the calculation results.
