To ensure safe operation of measuring instruments,
IEC 61010 establishes safety standards for various
electrical environments, categorized as O to CAT IV,
and called measurement categories. Higher-numbered
categories correspond to electrical environments with
greater momentary energy, so a measuring instrument
designed for CAT III environments can endure greater
momentary energy than one designed for CAT II.
O : Circuits which are not directly connected to
CAT II : Electrical circuits of equipment connected
to an AC electrical outlet by a power cord.
CAT III : Primary electrical circuits of the equipment
connected directly to the distribution panel,
and feeders from the distribution panel to
CAT IV : The circuit from the service drop to the
service entrance, and to the power meter
and primary over-current protection device

Guaranteed accuracy range:
Most # alternating currents and voltages are
expressed in effective values, which are also
referred to as RMS (Root-Mean-Square) values.
The effective value is the square root of the
average of square of alternating current or voltage
values. Many clamp meters using a conventional
rec t ify i ng ci r cui t have " R MS" s c ale s for AC
measurement. The scales are, however, actually
calibrated in terms of the effective value of a sine
wave though the clamp meter is responding to the
average value. The calibration is done with a
conversion factor of 1.111 for sine wave, which is
found by dividing the effective value by the average
value. These instruments are therefore in error if the
input voltage or current has some other shape than
CF (Crest Factor) is found by dividing the peak
value by the effective value.
Examples: Sine wave: CF=1.414
Square wave with a 1: 9 duty ratio: CF=3

4. Preparation for measurement
4-1. Checking Battery Voltage
Set the Function Switch to any position other than
"OFF". When the display is clear without "BATT" mark,
showing battery voltage is enough. When the display is
blank or "BATT" mark is indicated, replace the batteries
according to Section 7, Battery Replacement.
The Sleep f e a ture au tomatically powers the
instrument off in about 15 min after the last switch or
key operation. Therefore, the display may be blank
even with the Function Switch set to a position other
than "OFF". To operate the instrument in this case,
turn the switch back to the "OFF" position, then to
any other position. Replace the batteries if nothing
was displayed after above operations.
4-2. Checking Switch Setting & Operation
Confirm the Function Switch is set to the correct
po sition,the instrument is set to the co rrect
measurement mode,and the Data hold function is
disabled. Otherwise,desired measurement cannot be
