LCD Digital Multimeter (220-0185) Controls and Functions Faxback Doc. # 16929 1. Digital display: a. Low BATTery indicator - lights when batteries are weak and need replacing. b. AC indicator - lights when you select the AC voltage/ current measurement. c. Measured input values - shows the measured value with decimal point and minus polarity indication (2999 maximum). d. Measuring unit indicators - lights to show the current measuring unit. e. Diode check indicator - lights in the diode check mode. f. Continuity indicator - lights during the CONTINUITY check mode. 2. Power switch: Turns the meter ON and OFF. Set to CONTINUITY for continuity check. 3. Range switch: Used for selecting ranges: Voltage: DC V 300mV, 3V, 30V, 300V, 3000V (Maximum measurable voltage is 1000V). AC V 3V, 30V, 300V, 3000V (Maximum measurable voltage is 750V). Current: 3mA, 30mA, 300mA, 10A Resistance: 300ohm, 3kohm, 30kohm, 300kohm, 3000kohm, 30 Mohm Diode Check 4. Function switch: Used for selecting functions: DC V, AC V, Diode CHECK, kohm, DCmA and ACmA. 5. Input (10A) jack: Connect (+) red lead for current measurement with the 10A setting of the range switch. 6. Input (-) jack: Connect (-) black lead for all measurements. 7. Input (+) jack: Connect (+) red lead here for all measurements except 10A range. 8. Battery/fuse Compartment: Open to install/replace fuse and/or batteries. 9. Fold-out Stand: Use to support the multimeter at a convenient viewing angle for benchtop use or to hang it up. Special Panel Markings (A) AC/DC Special markings has been added to the panel AMPS to remind you of the measurement limitations ONLY and safety. 10A MAX The maximum current that can be measured is UNFUSED DC/AC 10A. 10A range is not fuse-protected. (B) 750V To avoid electrical shock and/or instrument MAX damage, do not connect the common input GROUND Symbol terminal (-jack) to any source of more than 750V with respect to earth/ground. (C) EXCLAMATION Symbol Refer to complete operating instructions. (D) 1000V DC The maximum voltage that can be measured is 750V AC 1000V DC or 750V AC. The maximum current 300mA measurement at this terminal is 300mA. MAX (E) LIGHTING BOLT Be extra careful when making measurements for Symbol high voltage; DO NOT TOUCH TERMINALS OR PROBE ENDS.
