Page 1: Digital Multimeter
DIGITAL MULTIMETER AX-588 OPERATION MANUAL... - Page 2 1. Sumary His series product is a stable and battery-driven 3 ½ digital multimeter with high reliability. It adopts LCD screen with character height of 28mm; with functions including unit sign/backlight and overload protection, it is easy to use. This series of device can be used to measure DCV, ACV, DC, AC, resistance, capacitance, inductance, diode, triode, open circuit, temperature and frequency, as well as hold peak value.

- Page 9 2-3-11. Measuring triode’s hFE parameter Range Display range Test condition hFE NPN lub PNP 0 ÷ 1000 Base electrode current is abort 10uA, and Vce is about 3V 5. Operation method 5-1. Operation panel introduction 1. LCD: display the measured value and the unit 2.
- Page 10 3) Popup the key “DC/AC” to enter into DC mode if measuring DC. Press down the key “DC/AC” to set into AC mode. 4) The screen will show the voltage measured if touch the testing point using the pencils; the point touched by the red pencil is in positive voltage if the value showed is positive.
- Page 11 Notice: 1)“OL” will be displayed in screen if the resistance is over the range, then you shall increase the range by one step. 2)When input is open circuit, it will display status of overload. 3)When measuring resistance on line, ensure that all power of circuit tested are turn down and all capacitor are discharged completely.
- Page 12 3) If in range 2mH, please short pencils and measure lead inductance, and then subtract the inductance from the value measured. 4) Avoid measuring small inductor in high range, or the accuracy is not guaranteed. 5-7. Temperature measurement Turn the switch to “°C”, insert the cathode (black pin) of cold end (free end) of thermocouple into “mA”...
