RM1307731648914587

1. Product Description

This Tester is a small tool design for Engineer, Electronic Maintenance and Factory,It’s very easy to test plug-in and SMD devices, also can test different kinds of Diodes, Triodes, Thyristors, MOSFET; able to analysis the device type, the polarity of the pin, the output HFE,

the valve voltage, the junction capacitance of the FET

2. Attention

● Always be sure to discharge capacitors before connecting them to the Tester!

● If using DC supply please choose DC 9V-12V adapter

.

● When the battery power is under 6V, please replace a new one

4 Use Introduction

a. Power ON: Pre “POWER/TEST” button before to use, this meter design 2“POWER/TEST” button, the function is the same. Easy for both left and right hand habit people to use.

b. Test: Pre “POWER/TEST” button to start a test. Regardle of the pin sequence, this meter will recognizes the pin’s function and layout on the screen.

c. Power OFF:

Automatically power down if no button operation in 20 seconds.

d. Test Socket: With 3 test sockets, SMD Socket, Plug-in Devices Socket and Probe Socket.

The port 1, 2, 3 of each socket are the same, they are connected internal.

e. SMD Device Test: Test via SMD socket or Probe. While using SMD socket, put some preure on device for better connection

f. Electrolytic Capacitor Discharge: Support max 2000μF/50V capacitor discharge with the internal 1K/1W resistor, and discharge for 2 seconds at least. Use external discharger while the capacity is higher

Discharge is stand alone function, no need to power on or pre button

g. Selection Menu:A long button pre(>0.5s) will enter the selection menu for additional functions. Short button pre to switch different functions,and long button(>0.5s) to enter submenu.

● Switch off: Long button pre to Power Off immediately

.● Transistor Exit Selection Menu, return to transistor test.

● Frequency:Reserved.

●f-Generator:With the button pre can select different frequencies output from T2(Test Port 2), and T1,T3 will be the reference gr-ound.

Frequencies selectable from1 Hz to 2 MHz

, amplitude is 5V

● 10-bit PWM: Generates a 7.8KHz frequency with selectable pulse width at the pin T2. With a short button pre (0.5s,
