To ensure that the meter is used safely, be sure to observe
the instruction when using the instrument.
1. Never use meter on the electric circuit that exceed 6kVA.
2. Never apply an input signal exceeding the maximum rating
input value.
3. Never use meter if the meter or test leads are damaged or broken.
4. Pay special attention when measuring the voltage of AC 33
Vrms (46.7V peak) or DC 70V and over avoid injury.
5. Never use meter for measuring the line connected with
equipment (i.e. motors) that generates induced or surge
voltage since it may exceed the maximum allowable voltage.
[1] SAFETY PRECAUTIONS
*Before use, read the following safety precautions.
This instruction manual explains how to use your new digital

16. Never use uncased meter.
17. Be sure to use a fuse of the specified rating or type. Never use
a substitute of the fuse or never make a short circuit of the fuse.
18. When connecting and disconnecting the test leads, connect
the ground lead (black one) first. When disconnecting them,
the ground lead must be disconnected last.
19. Always keep your fingers below the finger guards on the
probe when making measurements.
10. Be sure to disconnect the test pins from the circuit when
changing the function.
11. Before starting measurement, make sure that the function and
range are properly set in accordance with the measurement.
12. Never use meter with wet hands or in a damp environment.
13. Do not use the device near an item of strong
electromagnetic generation or a charged item.
14. Never open tester case except when replacing batteries or
fuse. Do not attempt any alteration of original specifications.
15. To ensure safety and maintain accuracy, calibrate and check
the tester at least once a year.
16. The multimeter is restricted to indoor use only.

[2] APPLICATION AND FEATURES
2-1 Applications
This instrument is portable digital multimeter designed for
measurement of weak current circuits. It plays an important role in
circuitry analysis by using additional functions as well as
measurements of small type communication equipment, electrical
home appliance, lighting voltage and batteries of various type.
2-2 Features
<PC500 / PC510>
The instrument meets the requirements to Safety Standard
IEC61010.
The main unit case and the circuit board are made of fire
retarding materials.
Fuse protects the current function.
Large digit for easy readings
Fast Response; Digit: 5 times/sec., Bargraph: 60 times /sec.
Frequency measurement with 5 selectable sensitivity (Sine
RMS)
Capacitance measurement ranges are 50.00nF to 9999µF.
0.01Ωof resistance and 0.01mV of AC/DC resolution
RS-232C interface
<PC510 only>
AC coupling True RMS
Temperature measurement (K-type)
MAX/MIN Recording through Auto range

[4] DESCRIPTION OF FUNCTIONS
4-1 Function Switch
Turn this switch to turn on and off the power and to select the
functions of "V /V /mV/ • /Temp(PC510)/Ω• /A/mA/µA".
4-2 Auto Power Off
The Auto Power Off mode turns the meter off automatically to
extend battery life after approximately 17 minutes of no activities.
Activities are specified as:
1) Changing sw potion or pressing a button.
2) Significant measuring data readings of around 10% of range.
To wake up the meter from Auto Power Off, press the SELECT
button momentarily or turn the rotary switch to the OFF position
and then turn back on again.
To disable the Auto Power Off feature, press the RANGE button
while turning the function switch on.
Note:
Always turn the function switch to the OFF position when the
meter is not in use.
4-3 Low Battery Indication
If the internal battery has been consumed and the internal battery
drops below approx. 7V, BATTERY mark is shown in the display.
4-4 Measurement Function Select
When the SELECT button is pressed ( ), the functions change
as follows.
•In the case of mV, µA, mA and A, the modes change as:
.
•In the case of Ω/ , the modes change as:
ΩΩ.
•In the case of / , the modes change as:

4-5 Range Hold
Press the RANGE button momentarily to set the manual range
mode then 'AUTO' disappears in the display. In manual range
mode, press the button again to step through the ranges. To
return to the auto mode, press the button for 1 sec. or more then
AUTO is shown.
Note:
Manual mode is not available in Hz measurement.
4-6 Data Hold
When the HOLD button is pressed, the data display at that time is
hold ('H' is shown on the display). The display will not changed
while the function is active. Press the button again to cancel the
function. ('H' on the display disappears.)
4-7 Auto Lead Resistance Calibration
When entering the 50Ωrange manually by RANGE button for
high precision low resistance measurement, this feature will
prompt you to short the inputs for calibration. The display shows
"Shrt". Simply short the leads for about 3 seconds until the display
shows zero, then the resistance in the leads and in the internal
protection circuitry of the meter is compensated automatically.
The compensation value can be as much as 5Ω. PC510:If you
need a compensation value that is higher than that, Relative
mode is recommended.
