AMM-1022 beforehand, set the range selector at the highest position. - “ ” means the socket of INPUT maximum current is 200mA, over current will destroy the fuse. 10A’s maximum current is 10A, no fuse protection. 4.3 Resistance measurement - Connect the black test lead to the COM jack and the red test lead to the Ω... -
Page 14: Continuity Test
AMM-1022 the cathode of the diode under testing. - The meter will show the approx. forward voltage of the diode. If the lead connection is reversed, only figure "1" displayed. To avoid electrical shock and/or damage to the instrument, disconnect circuit power and discharge all high-voltage capacitors before testing diodes. -
Page 15: Transistor Measurement
AMM-1022 plug to the COM jack and the red one to the TEMP jack, touch the end of the temperature sensor to the area or surface of the object for measurement. - You can get reading from LCD. To avoid electrical shock, do not connect the thermocouples with the electriferous circuit. -

AMM-1022 5. MAINTENANCE 5.1 General Maintenance Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Dirt or moisture in the terminals can affect readings. To clean the terminals: - Turn the meter off and remove all test leads. - Page 17 AMM-1022 5.3 Battery replacement To replace the battery (see the Figure): - When the battery voltage drop below proper operation range the symbol will appear on the LCD display and the battery need to be replaced. - Turn the meter off and remove all test leads.
- Page 18 AMM-1022 CAUTION Using this appliance in an environment with a strong radiated radio-frequency electromagnetic field (approx. 3V/m), may influence its measuring accuracy. The measuring result can be strongly deviating from the actual value.
