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 3kVA.
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 30
Vrms (42.4V peak) or DC 60V or more to avoid injury.

[1] SAFETY PRECAUTIONS
*Before use, read the following safety precautions.
This instruction manual explains how to use your new digital
multimeter PC5000 safely. Before use, please read this manual
thoroughly. After reading it, keep it together with the product for
reference to it when necessary. The instruction given under the
heading " WARNING" must be followed to prevent accidental burn
or electrical shock.
1-1 Explanation of Warning Symbols
The meaning of the symbols used in this manual and attached to
the product is as follows.
: Very important instruction for safe use.
The warning messages are intended to prevent accidents to
operating personnel such as burn and electrical shock.
The caution messages are intended to prevent damage to the
instrument.
: Dangerous voltage (Take care not to get an electric shock
in voltage measurement.)
: Ground (Allowable applied voltage range between the input
terminal and earth.)
: Direct current (DC)
: Alternating current (AC)
: Fuse
: Double insulation (Protection Class )

15. 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.
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, first
connecting the ground lead (black one). When disconnecting
them, the ground lead must be disconnected last.
19. Always keep your fingers behind 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. Never open tester case except when replacing batteries or
fuse. Do not attempt any alteration of original specifications.
14. To ensure safety and maintain accuracy, calibrate and check
the tester at least once a year.
15. The multimeter restricts in use in indoor.

[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 •dBm/V /mV/ Hz•%/ /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) Function switch or push switch operations.
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 V /dBm, the modes change as:
V dBm V .
• In the case of V / , the modes change as:
V V V .
• In the case of mV / / , the modes change as:
.
• In the case of Hz/%, the modes change as:
Hz % Hz.

• In the case of Ω/ , the modes change as:
Ω.
• In the case of µA, mA and A, the modes change as:
.
4-5 Range Hold
Press the RANGE button momentary 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 (' ' is shown on the display). The display will not changed
while the function is active. Press the button again to cancel the
function. (' ' on the display disappears.)
4-7 Set Beeper Off
Press the Hz button while turning the function switch on to disable
the Beeper feature.
4-8 RS232C Interface
The instrument equips with an optical isolated interface port at the
meter back for data communication. Optional purchase KB-RS2
(RS232 cable) and PC Link or PC Link Plus (software) are
required for Data logging system. Refer to an instruction manual
in the PC Link or PC Link Plus for further details.
Note:
While data communication to PC, Capacitance readout can be
sent to PC correctly up to 500.0µF range because of low
response speed for large capacitance measurement.
