Electronic Measuring apparatus, and delivered in
the best condition after passed the inspection. This
instruction manual contains warnings and safety
rules which must be observed by the user to ensure
safeoperation of the instrument and retain it in safe
condition.
Therefore, read through these operating instructions
beforeusingtheinstrument.
WARNING
●

Measurement Category
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
greatermomentary energy,so a measuringinstrument
designedforCATIII environmentscanendure greater
momentaryenergythanonedesignedforCATII.
O
:Circuits which are not directly connected
tothemainspowersupply.
CAT II
:Electrical circuits of equipment connected
toanACelectricaloutletbyapowercord.
CAT III
:Primary electrical circuits of the
equipment connected directly to the
distribution panel, and feeders from the
distributionpaneltooutlets.
CAT IV
:The circuit from the service drop to the
service entrance, and to the power meter
andprimaryover-currentprotectiondevice
(distributionpanel).

4. Preparation for measurement
4-1. Checking Battery Voltage
Set the Function Switch to any position other than
"
OFF
".When thedisplayis clearwithout "
BATT
" mark,
showing, battery voltage is enough. When the display
is blank or
"
BATT
" mark is indicated, replace the
batteriesaccordingtoSection7,BatteryReplacement.
CAUTION
The Sleep feature automatically powers the
instrumentoffinabout 15minafterthe lastswitch
or key operation. Therefore, the display may be
blankevenwiththeFunctionSwitchsettoaposition
other than "
OFF
". To operate the instrument in this
case, turn the switch back to the "
OFF
" position,
thentoanyotherposition,orpressanykey.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
position, the instrument is set to the correct
measurementmode,
and the Data hold function is disabled. Otherwise,
desiredmeasurementcannotbemade.
5. Measurement
5-1. AC Current Measurement
DANGER
●
Never make measurement on a circuit in which
voltage over AC600V exists to avoid getting
electricalshock.
●
Transformer jaw tips are designed not to short
the circuit under test. If equipment under test has
exposedconductiveparts,however,extraprecaution
should be taken to minimize the possibility of
shorting.
●
Do not make measurement with the Battery Cover
removed.
●
Disconnect the test leads from the instrument for
currentmeasurement.
●
Keep yourfingersand handsbehindthe barrieron
theinstrumentduringameasurement.
