【1】 SAFETY PRECAUTIONS : Before use, read the following safety precautions This instruction manual explains how to use your multimeter PC20 safely. Before use, please read this manual thoroughly. After reading it, keep it together with the product for reference to it when necessary.
07. 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. 08. Always keep your fingers behind the finger guards on the probe when making measurements.
2 APPLICATION AND FEATURES 2-1 Application This instrument is portable multimeter designated for measurement of weak current circuit. 2-2 Features ・The instrument has been designed in accordance with the safety standard IEC 61010-1.(See P48 "Safety") ・4000 counts disply. ・With the capacity measurement function. ・The current function is the semi auto ranges.

WARNING Do not change over the function switch with a voltage applied to the measuring terminals. The PC20 does not have the auto power-off function. When measurement is finished, be sure to return the function switch to the OFF position.
4-2 Connection with the personal computer WARNING Maximum input voltage in the event that is connect with computer is DC300V, AC220V (AC voltage is regulated by rms value of sinusoidal wave. Peak max. 310V) The multimeter is capable of DMM data communication using the RS232C / USB interface.
Fig 4 ② The incorporated battery and the AC adapter may be used together. Note, however, when the PC20 is used with the AC adapter only, the buzzer will not sound with such functions as the continuity check ( Insert the plug perpendicularly.
【5】MEASUREMENT PROCEDURE 5-1 Start-up Inspection WARNING 1. Never use meter if the meter or test leads are damaged or broken. 2. Make sure that the test leads are not cut or otherwise damaged. START ▼ Main unit and Damaged test leads damaged? ▼...
In the AC4V range, a figure of about 3~9 counts will stay on even if no input signal is present. But it is not malfunction. In the manual mode of the ACV function, the PC20 can be set to the 400mV range and shows an approximate value. But its accuracy is not guaranteed.
5-3 Resistance Measurement (Ω) WARNING Never apply voltage to the input terminals. 1) Application Resistance of resistors and circuits are measured. 2) Measuring ranges 400Ω 40MΩ (6 ranges) 3) Measurement procedure (See Fig 8, page 11) ①Connect the black plug of the test lead to the COM input terminal and the red plug to the input terminal.
120Ω will be displayed. The input terminals release voltage is about 0.4V. The buzzer will not sound if the incorporated battery is removed form the PC20 and it is operated with the power supply of the AC adapter only. − 38 −...
It is therefore recommended that an object to measure (capacitor) be directly connected between the ( ) and ( measuring terminals of the PC20. As the capacitance increases, the measuring time becomes longer. Example: 2 to 4 seconds at 10 F...
5-7 Current Measurement ( A, mA, A) WARNING 1. Never apply voltage to the input terminals. 2. Be sure to make a series connection via load. (please see to above drawing) 3. Do not apply an input exceeding the maximum rated current to the input terminals.
DCA: 4 10A (2 ranges), ACA: 4 10A (2 ranges) 3) Measurement procedure (See Fig 14, page 17) ①Slide the safety cover of the PC20 to the left and insert the red plug of the test leads to the 4 10A measuring terminal and the black plug to the COM ( ) terminal.
④Set the 400mV range (at DC measurement) or 4V range (at AC measurement) with range hold switch. ⑤Select either 20A or 200A with selector knob of clamp probe. probe to make the display of the PC20 show "000.0". ⑥Open the clamp part, have electric wire (one line) clamped. − 42 −...
⑦Read the value on the display as follows. DC20A : multiplying by 0.1 AC20A : multiplying by 100 DC200A : multiplying by 1 AC200A : multiplying by 1000 ⑧After measurement, open the clamp part and release clamp probe from the electric wire. ⑨Turn the function switch of multimeter and selector knob of clamp probe to the position of OFF.
【6】MAINTENANCE WARNING 1. This section is very important for safety. Read and understand the following instruction fully and maintain your instrument properly. 2. The instrument must be calibrated and inspected at least once a year to maintain the safety and accuracy. 6-1 Maintenance and inspection 1.
6-3 How to Replace Battery and Fuse (See Fig 19, page 23) WARNING 1. If the rear case is removed with input applied to the input terminals, you may get electrical shock. Before starting the work, always make ure that no inputs is applied. 2.
6-4 Cleaning and Storage CAUTION 1. The panel and the case are not resistant to volatile solvent and must not be cleaned with thinner or alcohol. For cleaning, use dry, soft cloth and wipe it lightly. 2. The panel and the case are not resistant to heat. Do not place the instrument near heat-generating devices (such as a soldering iron).
