EK Measurement of electrical resistance Insert the connector of black test probe into COM jack and insert red test the probe into Vil jack The polarity of the red probe is considered positive Select the desired measuring range by setting the rotary switch to the appropriate scale division it 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 measured resistance is found in the circuit before the measurements turn the power off and discharge all the containers in the circuit 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 Overload protection is triggered at 250 V DC or AC RMS value less than in 10 seconds Open circuit voltage is less than 2 8 V Check of 1 5 V and 9 V batteries Insert the connector of black test probe into COM jack and insert red test the probe into VO jack The polarity of the red probe is considered positive Set the range switch to 9 V or 1 5 V position Press the test probes to the poles of the battery and on the display read the voltage which battery gives under load Upon completion the work set the rotary switch in the OFF position Note Test conditions 1 5 operating current of about 40 mA 9 V operating current of about 24 mA Check of circuit continuity sound continuity test 0 Insert the connector of black test probe into COM jack socket and insert red test the probe into Vil jack Turn the rotary switch to position Connect the test probes to two points of the circuits to be checked If the resistance is less than 30 Ohms you hear a sound signal Upon completion the work set the rotary switch in the OFF position Diode check Insert the connector of black test probe into COM jack socket and insert red test the probe into Vil jack The polarity of the red probe is considered positive Set the function switch to M position Connect the red probe to the anode of the diode and the black probe to the cathode 16
