Before use, read the following safety precautions This instruction manual explains how to use your multitester CX506a, safely. Before use, please read this manual thoroughly. After reading it, keep it together with the product for reference to it when necessary.
1-2 Explanation of Warning Symbols The meanings of the symbols used in this manual and attached to the product are 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.
[2] APPLICATION AND FEATURES 2-1 Applications T h i s i n s t r u m e n t i s p o r t a b l e m u l t i m e t e r d e s i g n a t e d f o r measurement of weak current circuit.
[5] DESCRIPTION OF FUNCTIONS 5-1 Selectors, adjusters and switches ①Function/Range selector Turn the instrument on by selecting any measurement range. ②Meter zero position adjuster Turn the adjuster to have the pointer align with the zero line. (scale left edge) ③0 Ω・C∞Adjuster For resistance or hFE measurement, turn the adjuster to have the pointer align with the zero line (0 Ω) while test leads are shorted.
[6] MEASUREMENT PROCEDURE 6-1 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. 6-2 How to select an appropriate range (Selection of a appropriate range) ①For voltage or current measurements, select a function/range selector is higher than the value to be measured.
