Changing/Installing Battery; Pre-Operation Inspection - RIDGID micro HM-100 Bedienungsanleitung

Changing/Installing Battery

The RIDGID® micro HM-100 Tempera-
ture Humidity Meter is supplied without
the battery installed. When the low bat-
tery [ ] icon appears on the display
screen, replace the battery. Operating
the meter with a low battery can cause
incorrect readings. Remove the battery
prior to long-term storage to avoid bat-
tery leakage.
1. Switch OFF the device.
2. Use a Phillips head screwdriver to
loosen the battery compartment
cover screw and remove the cover.
Remove existing battery (See Figure 5).
3. Install 9V alkaline battery (NEDA 1604, IEC 6F22 or 6LR61), observing the correct polar-
ity as indicated on the battery compartment.
4. Securely install the battery compartment cover. Do not operate without the battery
cover secured.

Pre-Operation Inspection

Before each use, inspect your tool and correct any problems to reduce the risk of
serious injury or incorrect measurements.
1. Make sure the unit is OFF.
2. Clean any oil, grease or dirt from the equipment. This aids inspection and helps pre-
vent the tool from slipping from your grip.
3. Inspect the tool.
• For any broken, worn, missing or binding parts or any condition which may prevent
safe and normal operation.
• Confirm that battery compartment cover is properly secured.
• Check that the markings and warning label are present, firmly attached and read-
able.
If any issues are found during the inspection, do not use the tool until it has been properly
serviced.
4. Verify the meter operation (following the Operating Instructions)
• Turn the unit ON and confirm that the Low Battery icon is not ON.
• Measure a known temperature value.
5. Do not use the meter if it operates abnormally. When in doubt, have the meter
serviced.
