1. SAFETY INSTRUCTIONS This meter has been designed for safe use but must be operated with caution. The rules listed below must be carefully followed for safe operation. 1. NEVER apply voltage or current to the meter that exceeds the specified maximum: maximum: Input Limits Function... -
Page 5: Controls And Jacks
This symbol advises the user that the terminal(s) so marked must not be connected to a circuit point at which the 500V voltage with respect to earth ground exceeds (in this case) 500 VAC or VDC. This symbol adjacent to one or more terminals identifies them as being associated with ranges that may, in normal use, be subjected to particularly hazardous voltages. -

7.2. 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. -

7. Read the current in the display. For mA DC measurements, reset the function switch to successively lower mA DC positions to obtain a higher resolution reading. The display will indicate the proper decimal point and value. 7.4. RESISTANCE MEASUREMENTS WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements. -

7.7. BATTERY TEST 1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive V jack. 2. Select the 1.5V or 9V BAT position using the function select switch. 3. - Page 12 MAJOR TECH (PTY) LTD South Africa Australia www.major-tech.com www.majortech.com.au sales@major-tech.com info@majortech.com.au...
