Page 9: Dc Current Measurement
DC CURRENT MEASUREMENT Connect the red test lead to the “V.Ω.mA” jack and the black test lead to “COM” jack. (For measurements between 200mA and 10A, remove red lead to“10A” jack.) Set the rotary switch at desired DCA position. Open the circuit in which the current is to be measured, and connect test leads in series with the circuit. -
Page 10: Resistance Measurement
RESISTANCE MEASUREMENT Connect the red test lead to “V. Ω. mA” jack and black test lead to the “COM” jack. (The polarity of red lead is positive “+”.) Set the rotary switch at desired ”Ω” range position. Connect test leads across the resistor to be measured and read LCD display. - Page 11 in the bottom of the case. Simply remove the old, and replace with a new one. Be careful to observe battery polarity. WARNING Before attempting to open the case, always be sure that test leads have been disconnected from measurement circuits. Close case and tighten screws completely before using the meter to avoid electrical shock hazard.
