EK Measurement of direct and alternative voltage Insert the connector of black test probe in COM jack and insert the connector of red test the probe into V O Hz n jack The polarity of the red probe is considered positive With the use of the turning switch select the desired limit of measurement of DC V or AC V voltage Connect the test probes in parallel to the voltage source or load On the display read the indications of value and polarity of the measured voltage Upon completion the work set the rotary switch in the OFF position Notes When you install the switch in position 600 V HV and V signs will appear on the display reminding of the work with high voltage Caution is reg ui red If the voltage is not known beforehand set the switch of limits to the position of maximum voltage then switching to smaller limits adjust the required accuracy of measurements If the display shows only the digit 1 in the left it means that there is an overload and it is necessary to set the range switch to a higher volume Measurement of electrical resistance Insert the connector of black test probe into COM jack and insert red test the probe into VQHz F jack The polarity of the red probe is considered positive Select the desired measuring range by setting the rotary switch to an appropriate scale division Q and connect the test probes to different ends of the conductor to be measured On the display read the indication of value and polarity of the measured resistance of the conductor Upon completion the work set the rotary switch in the OFF position A ATTENTION If the resistance value is make sure that the power of the tested circuit is off and the capacitors are fully discharged Notes If the measured resistance value is greater than the maximum value of the selected measure limit the display will show the digit 1 in the higher order If the measured resistance is 1 Ohm or more the multimeter needs a few seconds to stabilize the voltage It is normal for high resistances 22
