4. How to Read Scales

※1 ：The thick portion of the scale indicates the allowable range of

voltage of a battery. (The lower limit of voltage for a 1.5V dry
battery specified by IEC 60086 is 0.9V.) Note that satisfactory
indication on the meter may not mean the battery has enough
power for high load (high current consumption) application.

5. Preparation

●Checking Test Leads and Fuse

Plug the red test lead into the + terminal and the black test lead into the -terminal,
and set the function selector switch to a position in the Ω area. Then, short the test
lead tips. When the meter pointer deflects to the right, proceed to measurement.

When the meter pointer does not deflect, replace the fuse with the spare fuse,
which is supplied with the instrument. If there is still no deflection, the test leads
may have an open. Replace the test leads.

●Adjusting Meter Pointer Zero

Turn the zero adjust screw to set the meter pointer to the "0" mark on the
extreme left of the scale for accurate measurement.

●Checking Function Selector Switch Setting

Make sure to set the function selector switch to the appropriate position.
Otherwise, intended measurement cannot be made, or injury or instrument
damage may result.

When the order of voltage or current under test is unknown, first make
measurement on the highest range, and then select the appropriate range.

6. How to Make Measurements

Voltage Measurements (ACV, DCV)

●Do not make measurement on a circuit above 600V AC or DC.

●Do not apply voltage that exceeds the rated voltage of the selected range.

●Do not turn the function selector switch during measurement.

●Do not touch the metal parts of the test leads during measurement.

●When the order of the voltage under test is unknown, make measurement

on the highest range.

(1)

Plug the red test lead into the + terminal and the black test lead into the -terminal.
(2)Set the function selector switch to the appropriate DCV or ACV position.
(3)Connect the test leads to the circuit under test so the instrument is in parallel

with the circuit. In DCV measurement, the meter pointer deflects to the right

(normal direction) when the red test lead is connected to the positive side of the

circuit under test and the black test lead to the negative side of the circuit.

Connecting the test leads the other way will reverse the pointer deflection.
(4)Take reading on the appropriate scale.

Current Measurements (DCA)

●

Exercise caution not to apply voltage to the instrument set to a current range.

●Do not turn the function selector switch knob during measurement.

●Make sure to firmly connect the test leads to the circuit under test so that the

connections will not become loose. The test leads must be connected to or
removed from the circuit under test with the circuit powered off.

●When the order of the current under test is unknown, make measurement on

the highest range.

(1)

Plug the red test lead into the + terminal and the black test lead into the -terminal.
(2)Set the function selector switch to the appropriate DCA position.
(3)Power off the circuit under test.
(4)Connect the test leads to the circuit under test so the instrument is in series with

the circuit. In DCA measurement, the meter pointer deflects to the right (normal

DANGER

direction) when the red test lead is connected to the positive side of the circuit
under test and the black test lead to the negative side of the circuit. Connecting

the test leads the other way will reverse the pointer deflection.
(5)Power on the circuit under test.
(6)Take reading on the appropriate scale.

Resistance/Continuity Check

●

Exercise caution not to apply voltage to the instrument set to a resistance range

●Make sure to power off the circuit under test.

― Resistance Measurement ―

(1)

Plug the red test lead into the + terminal and the black test lead into the -terminal.
(2)Set the function selector switch to the appropriate resistance position.
(3)Short the test lead tips. Turn the Ohm Zero Adjust Knob to set the meter

pointer to the "0" mark on the extreme right of the scale for accurate

measurement. Make this adjustment whenever the function selector switch is

turned to a different resistance position. When the zero adjustment cannot be

made, replace the batteries.
(4)Connect the test leads to the circuit under test.
(5)Take reading using the appropriate multiplying factor.

Note: Note that keeping the test lead tips shorted will exhaust the internal batteries.

― Continuity Check ―

(1)

Plug the red test lead into the + terminal and the black test lead into the -terminal.
(2)Set the function selector switch to the ' ' position.
(3)Connect the test leads to the circuit under test.
(4)Check if there is a sound of the buzzer. The buzzer beeps below about 100Ω.

Note: The meter does not read on this range.

― LED Check ―

(1)

Plug the red test lead into the +terminal and the black test lead into the - terminal.
(2)Set the function selector switch to the x10 position.
(3)Connect the test leads to the LED under the light-up test.
(4)When the LED does not light up, connect the test leads the other way.

Note: Connect the red test lead to the anode of the LED and the black test lead

to the cathode. The meter deflection has no meaning on this range.

― Temperature (TEMP.) Measurements ―

(1)

Plug the red test lead into the +terminal and the black test lead into the - terminal.
(2)Set the function selector switch to the x10 position.
(3)

Short the test lead tips. Turn the Ohm Zero Adjust Knob to set the meter pointer

to the "0" mark on the extreme right of the scale for accurate measurement.
(4)Remove both red and black test reads from the instrument.
(5)Plug the red lead of temperature probe Model 7060 to the + terminal and the

black lead to the-terminal.
(6)Touch the object under test with the tip of the temperature probe and take

reading on the TEMP scale.

Battery Test (BATT. TEST 1.5V)

This range measures the voltage of a battery, applying a load similar to that used
in common applications (load resistance: 10Ω).

●Do not apply voltage above the rated voltage for the battery test.

●Do not turn the function selector switch during a test.

(1)

Plug the red test lead into the + terminal and the black test lead into the - terminal.

.

(2)Set the function selector switch to the 'BATT. TEST 1.5V' position.
(3)Connect the red test leads to the positive side of the battery and the black test

lead to the negative side of the battery.

(4)Take reading on the BATT TEST scale.
Note: The less power a battery has, the lower the reading on this range becomes

compared to the reading on the 3V DC range.

7. Battery & Battery Replacement

●To avoid electric shock hazard, be sure to set the function selector switch to

the OFF position and remove the test leads from the instrument.

●Replacement fuse must have the following rating.
Fast acting type, F500mA/600V,φ6.3 ×32mm

●Do not mix new and old batteries.

●Install the batteries observing correct polarity shown inside the instrument.

(1)Remove the test leads from the terminals on the instrument and set the function

selector switch to the OFF position.

(2)Loosen the screw on the bottom of the instrument and remove the bottom case

from the instrument.

(3)Replace the batteries or fuse with new one(s). Use;

Two R6P dry batteries
A fast acting type fuse: F500mA/600V,φ6.3 ×32mm

(4)Mount the bottom case and tighten the screw.

Note: Use the spare fuse stored inside the instrument. After using the spare fuse,

store a new one as a new spare.
