cause injury or instrument damage.

DANGER

• Never make measurement on a circuit in which the electrical potential exceeds AC500V since this instrument is designed for

low voltage measurement.

• Do not make voltage measurements on industry power lines of 250V or higher.

• Do not attempt to make measurement in the presence of ﬂammable gasses.

Otherwise, the use of the instrument may cause sparking,

which can lead to an explosion.

• Caution should be taken not to short-circuit the power line with the test leads when measuring voltages. It may cause personal inju

ry.

• Never attempt to use the instrument if its surface or your

hand are wet.

Do not exceed the maximum allowable input of any

measuring range.

WARNING

• Never attempt to make any measurement if any abnormal conditions, such as a broken cover and test leads or exposed metal parts are present on the instrument.

• Do not install substitute parts or make any modiﬁcation to the instrument.

Return the instrument to your local KYORITSU distributor

for repair or

re-calibration in case of suspected faulty

operation.

6. CAUTION FOR USE

•

Make sure to check the fuse. With the range switch set to one of the ohm ranges short the tips of the test leads. When the pointer deﬂects to the right (zero mark on the ohm scale) the fuse is OK. If the pointer does not deﬂect at all replace the fuse with a new one (0.5A/250V) as it has blown.

•

When the pointer is positioned off the zero mark on the extreme left of the scale turn the zero adjust screw so that it is set to the zero position. The instrument will not give accurate readings when used without this zero adjustment.

• Before taking measurements make certain that the range switch has been properly set. Also, make sure to remove the test lead tips from the circuit, under test when switching over the range

during measurement. When the voltage is accidentally applied to the current or ohm ranges the fuse may blow or the instrument may get damaged.

7. HOW TO MAKE MEASUREMENTS

7-1 DC Voltage Measurements

⑴ Plug the red test lead into the plus terminal and the black test

lead into the minus terminal.

⑵ Set the range switch to DC 500V. ⑶ Connect the red test lead to the plus side of the circuit un

der

test and the black test lead to the minus side.

⑷ When the reading is below 250V set the range switch to

DC 250V and make the measurement. Follow the same measurement procedures with the range switch set to the desired position.

7-2 AC Voltage Measurements

⑴ Plug the red test lead into the plus terminal and the black test

lead into the minus terminal.

⑵ Set the range switch to AC 500V. ⑶ Con

nect the test lead to the circuit under test.

⑷ As in DC voltage measurements set the range switch to the

desired position and make the measurement.

7-3 DC Current Measurements

⑴ Plug the red test lead into the plus terminal and the black test

lead into the minus terminal.

⑵ Set the range switch to 250mA DC. ⑶ Connect the red test lead to the plus side of the circuit under

test and the black test

lead to the minus side.

⑷

When the measurement is possible on lower ranges set the range switch to the desired position and make the measurement.

7-4 Resistance Measurements

⑴ Plug the red test lead into the plus terminal and the black test

lead into the minus terminal.

⑵ Set the range switch to Ω. ⑶ Short the test lead tips. When the pointer is not positioned

over the zero mark on the ohm scale

turn the ohm zero adjust knob so that it is set to the zero position. When the pointer does not still read zero replace the battery with a new one as it is weak.

⑷ Connect the test leads to both ends of the circuit under test. ⑸ Set the range switch to the desired position and make the

measurement.

Note: Make sure to turn off power when the resistance of a

circuit is measured.

7-5 1.5V Battery

Test

⑴ Plug the red test lead into the plus terminal and the black test

lead into the minus terminal.

⑵ Set the range switch to 1.5V BATTERY TEST. ⑶ Connect the red test lead to the plus side of the battery and

the black test lead to the minus side for battery tests.

Note: 20Ω load resistor is used for 1.5V battery test.

7-6 Temperature Measurements

⑴ Insert red voltage test lead into plus

(+) terminal and black

voltage test lead into minus (−) terminal.

⑵ Set range switch to TEMP position. ⑶ Short the tips of test leads and turn ohm zero adjust knob so

that pointer is positioned on CAL mark of temperature scale (Fig. 3). After completing this procedure, remove test leads.

⑷ Insert red test lead of temperature probe Model 7060 into

plus (+) terminal and black test lead into minus (

−) terminal

(Fig. 4). Read temperature direct from temperature scale.

Note: Refrain from measuring the temperature of metal parts

having a voltage higher than 50V as it is dangerous.

8. FUSE & BATTERY REPLACEMENTS

• Where the fuse has blown remove the housing case and replace it with a new one.

Make sure to use the 0.5A /250V fuse as speciﬁed. The use of

any other substitute may damage the instrument.

• When the battery is weak the ohm zero adjustment becomes impossible. Accurate resistance and temperature measurements cannot be made without the ohm zero adjustment. Remov

e the bottom case for replacement of the

weak battery with a new one.

9．CLEANING METER COVER

Do not try to remove dirt on the meter cover by rubbing hard with a dry cloth. This can remove anti-electrostatic agent applied to the surface of the surface of the meter cover.

When the meter reading is affected by electrostatic build up on the meter cover. Wipe the meter cover surface using a cloth dampene

d with offthe shelf anti-static agent or detergent. To avid possible deforming or discoloring, do not use solvents.

To clean the body of the instrument, use cloth dampened with detergent.

CAUTION

Never use paint thinner, benzene or other solutions containing solvents for cleaning the instrument. Otherwise, deforming or discoloring of the instrument body or the meter cover may result.

Note:

Handle the instrument with care and follow the instructions in order to maintain it in good condition for a long period of time.
