EK Shut off the circuit to be measured and connect the test probes of the device in series on load which is used to measure the current Read the indications of magnitude and polarity of the measured current strength on the display Upon completion the work set the rotary switch in the OFF position Notes If the current value is not known beforehand set the limits switch to the position 10 A insert the red probe into the jack 10 A and then switching to smaller limits adjust the required accuracy of measurements If the display shows only the digit 1 in the left digit it means that thee is an overload and it is necessary to set the range switch to a higher volume Measurement of DC and AC voltage Insert the connector of black test probe in COM jack and insert the connector of red test the probe into VOmA jack The polarity of the red probe is considered positive With the use of the rotary switch select the desired limit of measurement of DCV 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 positron Notes When you install the switch in position 600 V HV and signs will appear on the display reminding of the work with high voltage Caution is required 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 equired accuracy of measurements If the display shows only the digit 1 in the left digit it means that thee 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 in COM jack and insert the connector of red test the probe into VOmA jack The polarity of the rod probe is considered positive Select the desired measuring range of resistance Q with the rotary switch Connect the test probes to different ends of the conductor to be measured and read the display indications 17
