Page 10: Mode Button
NOTE: On some low AC and DC voltage ranges, with the test leads not connected to a device, the display may show a random, changing reading. This is normal and is caused by the high-input sensitivity. The reading will stabilize and give a proper measurement when connected to a circuit. 6.1. -
Page 11: Ac Voltage Measurements
6.6. AC VOLTAGE MEASUREMENTS WARNING: Risk of Electrocution. The probe tips may not be long enough to contact the live parts inside some 240V outlets for appliances because the contacts are recessed deep in the outlets. As a result, the reading may show 0 volts when the outlet actually has voltage on it. -

6.8. AC CURRENT MEASUREMENTS WARNING: To avoid electric shock, do not measure AC current on any circuit whose voltage exceeds 250V AC. CAUTION: Do not make current measurements on the 10A scale for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads. -

6.10. RESISTANCE MEASUREMENTS WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements. Remove the batteries and unplug the line cords. Set the function switch to the Ω position. Insert the black test lead banana plug into the negative (COM) jack and the red test lead banana plug into the positive Ω... -
Page 14: Temperature Measurements
6.13. TEMPERATURE MEASUREMENTS WARNING: To avoid electric shock, disconnect both test probes from any source of voltage before making a temperature measurement. If you wish to measure temperature in °F, set the function switch to the °F range. If you wish to measure temperature in °C, set the function switch to the °C range. -
Page 15: Replacing The Fuses
Insert the battery into battery holder, observing the correct polarity. Put the battery cover back in place. Secure with the two screws. WARNING: To avoid electric shock, do not operate the meter until the battery cover is in place and fastened securely. NOTE: If your meter does not work properly, check the fuses and battery to make sure that they are still good and that they are properly inserted. - Page 16 MAJOR TECH (PTY) LTD South Africa Australia www.major-tech.com www.majortech.com.au sales@major-tech.com info@majortech.com.au...
