Page 9: 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 10 A-H Button In Auto hold mode, the meter will capture and hold the first stable non- zero(>100 digits) reading after a zero reading(<100 digits). Several consecu- tive measurements can be held and displayed without pressing the (A-H) buttion. Simply by shorting the test leads together between measurements. Press (A-H) to toggle in and out of the Auto Hold mode.
- Page 11 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/Range switch to the desired voltage function. 3. Connect the test leads to the device or circuit being measured. 4.
- Page 12 Diode Tests 1. Connect the red test lead to the "VW " jack and the black test lead to the "COM" jack. 2. Set the Function/Range switch to the " " position. 3. Turn off power to the circuit under test. 4.
- Page 13 Inductance Measurements 1. Set the Function/Range switch to the desired "H" (inductance) range. 2. Never apply an external voltage to the Lx sockets. Damage to the meter may result. 3. Insert the inductor leads directly into the Lx socket. 4. Read the inductance directly from the display. Logic Measurements 1.

Page 14: 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 15 Additional Safety Information • Do Not Operate the meter with the two test leads and the thermocouple probe connected at the same time. Unplug the test leads from the meter before making thermocouple temperature measurement. Unplug the ther- mocouple probe from the meter before making other types of measure- ments.
