EK Transistors test Set the switch in hFE position Insert the adaptor supplied into hFE mA EdB C and COM jacks Determine the type of transistor as NPN or PNP and determine the outlets of emitter base and collector Correctly insert the transistor connector into the corresponding jacks on the front panel E emitter B base C collector of the transistor On the display read the approximate hFE value at the current of the base of 10 pAand Vee voltage of 3 2 V Upon completion the work set the rotary switch in the OFF position A ATTENTION Before you test the transistor remove probes from the jacks of the multimeter Check of circuit continuity sound continuity test HI Insert the connector of black test probe into COM jack socket and insert red test probe into V O Hz p jack Set the range switch to O position and connect the test probes to two points of the circuit to be measured If there is a galvanic connection between them i e the resistance between them is less than 50 Ohms you will hear a sound signal Upon completion the work disable the multimeter with OFF button OFF position Temperature measurement only for MY62 MY64 modifications Set the range switch to TEMP position and the indicator will show the ambient temperature Insert the adaptor supplied into hFE mAEfB C and COM jacks Attach the thermocouple of K type to the multimeter through the adapter Press the thermocouple to the object to be measured and read on the display the temperature value in Celsius degrees Upon completion the work remove the adapter from the multimeter jack Disconnect the multimeter button mute the OFF position ATTENTION To avoid electrical shock while changing the functions and measurement range make sure that the thermocouple is removed from the jack of the device 24
