measurement ranges. Either one of the test leads should be taken off from the circuit under test when changing the test ranges. 7) To avoid electrical shock or damage to the meter; Do not apply more then 500V between any terminal and earth ground. 8) To avoid electronic shock, use caution when working above 60VDC or 25VAC rms, such voltage pose a shock hazard. 9) When finished the measurement, switch off the power. Be sure to remove the battery when it is not used for a long time to avoid leakage problem.
polarity at the red test lead connection will be indicated at the same time as the current. Note: a) If the current range is unknown beforehand, set the function range switch to the highest range and work down. b) When only the figure “1” is displayed, over range is being indicated and the function range switch has be set to a higher range. c) Excessive current will below the fuse that must be replaced when the input is from “A” terminal. Fuse type is 0.5A (model MY-60 & MY-60T maximum 2A).
read the display value. Note: The tested capacitor should be discharged before the testing procedure. Never apply voltage to the “Cx” input socket, or serious damage may result. 5.5 FREQUENCY MEASUREMENT 1) Set the function range switch at the required “Hz” position. 2) Connect test leads to measuring points and read the display value. Note: Do not apply more than 250V rms to the input. Indication is possible a voltage higher than 100V rms, but reading maybe out of specification. 5.
c) voltage approx. 2.8V. The meter displays the forward voltage drop and displays figure “1” for overload when the diode is reversed. 5.8 TRANSISTOR hFE TEST 1) Set the function range switch to the “hFE” position. 2) Make sure the transistor is “NPN” or “PNP” type. 3) Transistor correct insert to E.B.C connector. 4) Display reading is approx. transistor hFE value. Note: Test condition: Base current approx. 10uA. VCE approx.2.8V 6.
OPERATOR’S MANUAL CAUTION: * Before attempting to insert transistors capacitor thermocouple for testing, always be sure that test lest leads have been disconnected from any measurement circuits. * Components should not be connected to the hFE and capacitor and the thermocouple socket when making voltage measure with test leads. *Using this appliance in an environment with a strong radiated radio – frequency electromagnetic field (approximately 3V/m), may influence its measuring accuracy.
1. SAFETY INFORMATIONS This multimeter has been designed according to IEC-1010 concerning electronic measuring instruments with an overvoltage category (CATⅡ) and pollution 2. Follow all safety and operating instructions to ensure that meter is used safely and is kept in good operating condition. 1.1 PRELIMINARY * When using this meter, the user must observe all normal safety rules concerning: －Protection against dangers of electronic current. －Protection of the meter against misuse.
1.4 MAINTENANCE * Before opening the meter, always disconnect test leads from all sources of electric current. * For continue protection against fire, replace fuse only with the specified and current rating: F200mA / 250V (quick acting) *If any faults or abnormalities are observed, the meter can not be used any more and it has to be checked out. *Never use the meter unless the back cover is in place and fastened fully. *Do not use abrasives or solvents on the meter use a damp cloth and mild detergent only.
2.1 2.2 2.3 FUNCTION AND RANGE SELECTOR There are different functions and 32 ranges provided. A rotary switch is used to select functions as well as ranges. POWER SWITCH A push-push switch is used to turn the meter on or off. To extend the battery life, Auto Power- Off function is provided (Optional). The meter will be turned off automatically within around 40 minutes. To turn on the meter again, push the power switch to release it and then push it once more.
The polarity of the red lead connection will be indicated along with the current value when making DC current measurement. 3. When only the figure”1” displayed, it indicates overrange situation and the higher range has to be selected. 3.3 MEASURING FREQUECY 1. Connect the black test lead to the COM jack and the red test lead to the VΩHz jack. 2. Set the rotary switch at kHz position and connect test leads across the source or load under measurement. NOTE: 1.
3.6 TESTING DIODE 1. Connect the black test lead to COM jack and the red test lead to the VΩHz jack (The polarity of red lead is〝+〞) 2. Set the rotary switch at position and connect red lead to the anode, black lead to the cathode of the diode under testing .The meter will show the approx. forward voltage of the diode. If the lead connection is reversed. only figure〝1〞 displayed. 3.7 TESTING TRANSISTOR 1. Set the rotary switch at hFE position. 2.

5.3 How to use the holster The holster is used to protect the meter and to make the measurement more comfortable. It comes with two stands installed together. The figure shows how to use the holster to: a. Support the meter with a standard angle. b. Support the meter with a small angle using the little stand c. Hang the meter on the wall using the little stand. Take the little stand off from the back side of the large stand and insert it into holes located upper on the holster. d. Hold test leads. -246.
