6.2. MAX/MIN NOTE: When using the MAX/MIN function in Auto ranging mode, the meter will “lock” into the range that is displayed on the LCD when MAX/MIN is activated. If a MAX/Min reading exceeds that range, an “OL” will be displayed. Select the desired range BEFORE entering MAX/MIN mode. -
Page 11: Ac Voltage Measurements
6.7. 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. -
Page 12: Ac Current Measurements
6.9. 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. -
Page 13: Diode Test
Touch the test probe tips to the circuit or wire you wish to check. If the resistance is less than approximately 100Ω, the audible signal will sound. The display will also show the actual resistance. 6.12. DIODE TEST WARNING: To avoid electric shock, do not test any diode that has voltage on it. -
Page 14: Temperature Measurements
6.15. 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 door 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...
