Precautions for Safety Measurement

! WARNING: Do not use the tester for the measurement of electric circuits of a large capacity. T the fuse contained in the tester is rated as 250V. Avoid measuring such circuits as there may be some problem that jeopardizes safety measurement due to a possible error in setting range.
! WARNING :Be sure to use a fuse of the specified rating and type (0.5A/250V. 5.2 ´ 20mm.) Never use a substitute or short the circuit.
! WARNING :Do not touch the test pin during measurement.
! WARNING :Be sure to use a fuse of the specified rating and type (0.5A/250V. 5.2 ´ 20mm.) Never use a substitute or short the circuit.
! WARNING :Never operate the tester with wet hands, at places with high humidity or much moisture. You may get electric shock.
! WARNING :Make sure that the coating of the cord of the test leads is not damaged of conductor is not exposed. If they are damaged or exposed, do not use the tester.
! WARNING :There is a danger of electric shock. Exercise special care when measuring voltage above 60 VDC or 25 Vrms AC.
! WARNING :Do not make a measurement with the rear case or the meter cover removed.
! WARNING :Each time you make a measurement, be sure to check ranges. Measurement with erroneous setting or beyond the measuring range is hazardous.
! WARNING :Take care not to cause an overload state when measuring voltage or current containing pulsating currents of pulses.

MEASURING PROCEDURE(DCV,ACV,DCA,Ohm,C,dB)

! WARNING : Confirm the range to use before measurement

Preparing for Measurement

1.
Adjustment of meter zero position.
Turn the zero position adjuster so that the pointer may align right to the zero position.

2.
Range selection:
Select a range proper for the item to be measured set the range selector knob accordingly.

Note:
When determining a measurement range, select such one for higher voltage than the voltage to be measured as well as where the pointer of a meter moves to a considerable extent. However, select the maximum range and measure in case the extent of value to be measured can not be predicted.

Measuring DCV

1.
Set the range selector knob to an appropriate DCV range.

2.
Apply the black test pin to the minus potential of measured circuit and the red test pin to the plus potential.

3.
Read the move of the pointed by V and A scale.

Measuring ACV

1.
Turn the range selector knob to an appropriate ACV range.

2.
Apply the test leads to measured circuit.

3.
Read the move of the pointer by V and A scale. (Use AC 10V scale for 10V range only.).

Since this instrument employs the mean value system for its AC voltage measurement circuit, AC waveform other than since wave may cause error.

There occurs error under such frequencies other than specified in the specification.

Measuring DCA

! WARNING : Connect the meter in series with load.

1.
Turn the range selector knob to an appropriate DCA range.

2.
Take out measured circuit and apply the black test pin to the minus potential of measured circuit and the red test pin to the plus potential.

3.
Read the move of the pointed by V and A scale.

Measuring Ohm

! WARNING : Do not measure a resistance in a circuit where a voltage is present.

1.
Turn the range selector knob to an appropriate Ohmrange.

2.
Short the red and black test pins and turns the 0Ohm adjuster so that the pointer may align exactly to 0Ohm. (if the pointer fails to swing up to 0Ohm even when the 0Ohm adjuster is turned clockwise fully, replace the internal battery witty a fresh one.)

3.
Apply the test pin to measured resistance.

4.
Read the move of the pointer by scale.

NOTE:
The polarity of +and-turns reverse to that of the test leads when measurement is done in Ohm range.

NOTE:
How to replace battery

Loosen the screws fixing the rear case and remove it.

Take out R6 (UM-3) dry battery.

Put back ther rear case where it was and fix it with the screws.

NOTE:
Be sure to use the same rated fuse in case a fuse other than the same rated one (see "SPECIFICATION") is used, error in indication occurs and/or circuit protection is made unable.

Measuring Capacitor(C)

Set the range selector knob to C(microF)

Measure capacitance by applying the test pin to the capacitor to be measured after 0Ohm adjustment made in the same manner as in the resistance measurement

The pointer moves full scale by the charge current to the capacitor. However, the pointer starts gradual; returning form a certain point. Read the then indicated maximum value on C (F) scale.

NOTE:
Be sure to short circuit the both ends of the capacitor for discharge prior to the initial measurement or in such case to measure after the measurement was once made.

NOTE:
Pay due attention to the polarity (+ and -) of the capacitor. (Connect +side of the capacitor to -side of the tester.)

Measuring AF Output (dB)

dB (decibel) is measured in the same way as ACV measurement reading the dB scale instead.
For measurement on the 10V range the dB scale (-10dB~+22dB) is read directly, but, when measured on the 20V range, 14dB is added. On the 250V range, 28dB is added to the reading on the scale, and on the 1000V range, 40dB added.
Thus, the maximum dB readable is 22+40 = 62 (dB) measured on the 1000V range.

NOTE:
Cut direct current with a capacitor of 0.1 mF or more when
measuring such signal as having direct current.

Measuring IcEO (Leak Current) for Transistor

Adjust 0Ohm by setting the range selector knob to a proper range from x 1~ x 1k.

For NPN transistor, apply a black test pin to the collector and a red one to the emitter. For PNP transistor, the red one to the collector and the black one to the emitter.

Determine the leak current by Iceo scale indicated on the scale plate. (Unit in microA, mA.)

Measuring of Diode (including LED)

Adjust 0W by setting the range selector knob to a proper range from x 1 (150mA)~ x 100K(1.5 microA.)

Apply the black test pin to anode side and the red one to cathode side when measuring IF (forward current.) Apply the black test pin to cathode side and the red one to anode side when measuring IR (reverse current.)

Read the indicated value by Li scale. )The pointer moves to a considerable extent for IF, and little extent for IR)

Value indicated on LV scale during the measurement is the forward voltage of diode.

USAGE OF OPTINAL PROBES

Usage of High Voltage Probe (HV-10T)

Up to DC 25kV of CRT anode voltage can be measured by connecting optional HV-10T probe.

! WARNING : Keep the hand (finger) away from high voltage power supply. Electric shock may occur due to discharge.

! WARNING : Measurement should be limited only to micro current circuits.

Usage of the Probe (HFE-6T)

Set the range selector knob to x 10 range (hFE PROBE)

Short circuit both the red and black test pin to adjust 0Ohm.

Connect the black test pin to the probe jack when a transistor to be measured is NPN, and the red pin to the probe jack for PNP transistor.

Connect the black clip of probe to the transistor base and the red clip to the collector.

Connect the remaining test lead to ther emitter and measure hFE.

Read the indicated value of the meter on hFE scale.

MAINTENANCE

How to Replace the Fuse

If an overload above lighting voltage (about 100V) is applied to DCA, and Ohm ranges, the fuse is blown to protect the circuit.

Loosen the screws fixing the rear case and remove it.

Pull out the fuse out of holder on the circuit board and replace it.

Put back the rear case where it was and tighten the screws.

Check and see whether or not indications of respective ranges are normal (check other parts for any failures.)

OTHERS

Use of Cover (example for the body cover)

When this tester is out of use:
Attach the cover to the panel face for safekeeping.

When measuring:
Attach it either to the rear case side or use it as a stand as illustrated.

Store of Tester Leads
When placing the test leads in the storing space, roll it 3 times, then put in the test pin side first for store in the place (test lead store space) as illustrated.
