EK At the limit of 200 MOhm at open probes the voltage is 3 V and when closing the probes the display will readout 10 During the measurements at this limit in order to obtain the correct result you should subtract 10 units from the readout Frequency measurement only for MY63 MY64 modifications Insert the connector of black test probe into COM jack and insert red test probe into VOHz M jack The polarity of the red probe is considered positive Set the range switch to position Hz and connect the probes to the signal source or load On the display read the values of frequencies Upon completion the work set the rotary switch in the OFF position Notes Measurement is possible if the input voltage exceeds the effective value of 10 V but the accuracy is not guaranteed It is preferably to use shielded cable when measuring small signals Capacity measurement Set the function switch to the position F Insert the adaptor supplied into hFE mAgB C and COM jacks of the multimeter Insert the capacitor into the socket of Cx adapter observing the polarity On the display read the values of the measured capacity of the capacitor Upon completion the work set the rotary switch in the OFF position A ATTENTION Before you install the capacitor into the measurement slot make sure that it is fully discharge Diode check Insert the connector of black test probe into COM jack and insert red test the probe into VQHz n j jack The polarity of the red probe is considered positive Set the function switch to the position n Connect the red probe to the anode of the diode and the black probe to the cathode Read on the display the approx forward voltage drop of the diode when the flow of direct current through it If the polarity of the diode is reversed then the display will show the digit 1 in the left Upon completion the work set the rotary switch in the OFF position 23
