Page 8: Operation
OPERATION Before taking any measurements, read the Safety Information Section. Always examine the instrument for damage, contamination (excessive dirt, grease, etc.) and defects. Examine the test leads for cracked or frayed insulation. If any abnormal conditions exist do not attempt to make any measurements. - Page 9 Voltage Measurements 1. Connect the red test lead to the "VW " jack and the black test lead to the "COM" jack. 2. Set the Function switch to the desired voltage type (DCV) or (ACV) position. 3. Touch the probes to the test points, the range will change automatically to the level that will display the input voltage with best resolution.
- Page 10 Resistance Measurements 1. Set the Function switch to the " W " position. 2. Turn off power to the circuit under test. External voltage across the components causes invalid readings. 3. Connect the red test lead to the "VW " jack and the black test lead to the "COM"...
- Page 11 Continuity Measurements 1. Set the Function switch to " " position. 2. Turn off power to the circuit under test. External voltage across the components causes invalid readings. 3. To toggle between the continity/diode modes, press Range Switch. 4. Connect the test leads to the two points at which continuity is to be tested. The buzzer will sound if the resistance is less than approximately 20W ±5W .

Page 12: Maintenance
MAINTENANCE WARNING Remove test leads before changing battery or fuse or performing any servicing. Battery Replacement Power is supplied by a 9 volt "transistor" battery. (NEDA 1604, IEC 6F22). The " " appears on the LCD display when replacement is needed. To replace the battery, remove the two screws from the back of the meter and lift off the battery case. - Page 13 CONDITIONS: Equipment sold by OMEGA is not intended to be used, nor shall it be used: (1) as a "Basic Component" under 10 CFR 21 (NRC), used in or with any nuclear installation or activity; or (2) in medical applications or used on humans.
