DBM2671 Insulation Resistance Tester

 Use the Meter only as specified in this manual or the protection provided by the Meter might be impaired.

 Do not use the Meter or test leads if they appear damaged, or if the Meter is not operating properly. If in doubt, have the Meter serviced.

 Always use the proper terminal, switch position, and range for measurements before connecting Meter to circuit under test.

 Verify the Meter’s operation by measuring a known voltage.

 Do not apply more than the rated voltage as marked on the Meter, between the terminals or between any terminal and earth ground.

 Use caution with voltages above 30 V ac rms, 42 V ac peak, or 60 V dc. These voltages pose a shock hazard.

 Replace the battery as soon as the low battery indicator ( ) appears.

 Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance.

 Do not use the Meter around explosive gas or vapor.

 When using the test leads, keep your fingers behind the finger guards.

 Remove test leads from the Meter before opening the Meter case or battery door.

 Never operate the Meter with the cover removed or the battery door open.

 Comply with local and national safety requirements when working in hazardous locations.

 Use proper protective equipment, as required by local or national authorities when working in hazardous areas.

 Use only the replacement fuse specified or the protection may be impaired.
