4 OvervoltageCategory III. Use the meter only as specified in thismanual, otherwise the protection provided by the metermay be Warning identifies conditions and actions that posehazard(s) to the user; a Caution identifies conditions andactions that may damage the meter or the equipmentunder symbols used on the meter and in thismanual are explained in Table avoid possible electric shock or personalinjury: Do not use the meter if it is you use the meter, inspect thecase. Look for cracks or missing particular attention to the insulationsurrounding the Information3 Make sure the battery door is closed andlatched before you operate the meter. Remove test leads from the meter beforeyou open the battery door. Inspect the test leads for damagedinsulation or exposed metal. Check testleads continuity. Replace damaged testleads before you use the meter.

5 Do not use the meter if it operatesabnormally. Protection may be in doubt, have the meter serviced. Do not operate the meter aroundexplosive gas, vapor, or dust. Use only a single 9V battery, properlyinstalled in the meter case, to power themeter. When servicing the meter, use onlyspecified replacement avoid possible damage to meter or toequipment under test:Disconnect the power and discharge all high-voltage capacitors before testing resistanceor the proper jacks, function, and range foryour measurement or sourcing application. To protect yourself, adhere to the following guidelines: Use caution when working above 30V ac rms, 42V acpk, or 60V dc. Such voltages pose a shock hazard. When using the probes, keep your fingers behind thefinger guards on the probes. Connect the common test lead before you connectthe live test lead.
