Resistance Meter (Zero Adjust)
Correction code 16300100
- 1076927-00-A Hioki RM 3548 (includes alligator clip leads L2107)
- 1076928-00-A Test Probes - Hioki 9461
- 1032801-00-B ASY,PROBE,CONTACTOR,200,3+1_POINT (if measuring contactor resistance)
- 1080510-00-A Resistance Block
- #GUID-87FD8D3D-05FF-471F-B2AC-EC4D65ED3E08 - The most commonly used method of zero adjust.
- #GUID-62BA0B0B-5667-4E7A-9377-FD16DF5909D4 - This method requires the resistance block special tool.
CAUTION
Never use the
resistance meter to measure voltage.
Zero Adjust With Alligator Clip Leads
- Power on the Hioki resistance meter, and allow a few minutes for it to thermally stabilize.
-
Plug the alligator clip
leads into the resistance meter.
NoteBoth the positive (red) and negative (black) lead connectors have arrows or marks that align to arrows on the resistance meter.
- Use the up arrow and down arrow buttons to set the resistance meter to the 3mΩ range.
- Attach the alligator clips together so that the red clip "bites" the upper jaw of the black clip, and that the "V" on each clip is up.
-
Verify that a resistance is
displayed.
NoteIf " -.- - - - " (no value) is displayed, check the lead connections to the resistance meter and the how the clips attach together.
-
Press and hold the 0ADJ
button to start the zero adjust operation.
NoteThe text "0 ADJ" blinks in the upper right corner of the resistance meter's display.
-
Approximately 2 seconds
later, the resistance meter beeps and "0 ADJ" is now constant.
NoteIf " FAiL " is displayed, check the clips, the leads, and the connection to the resistance meter, and repeat from step #GUID-87FD8D3D-05FF-471F-B2AC-EC4D65ED3E08__GUID-9B169B6A-5DB2-4049-94E4-EE4B14F2D359.
-
Detach the clips from each
other and unplug the leads from the resistance meter.
CAUTIONDo not change the range, otherwise the resistance meter must be zero adjusted again.
-
Plug the Hioki 9461 test
probe leads or the 3+1_point contactor probe leads into the resistance meter.
NoteAlign the arrows of the lead connectors to the arrows on the resistance meter.
- The resistance meter is now ready to measure resistance. Return to the procedure that required the zero adjust to be performed.
Zero Adjust With Resistance Block
- Power on the Hioki resistance meter, and allow a few minutes for it to thermally stabilize.
-
Plug the Hioki 9461 test
probe leads into the resistance meter.
NoteBoth the positive (red) and negative (black) lead connectors have arrows or marks that align to arrows on the resistance meter.
- Use the up arrow and down arrow buttons to set the resistance meter to the 3mΩ range.
-
Press and release the 0ADJ
button to start the zero adjust operation.
NoteThe text "0 ADJ" blinks in the upper right corner of the resistance meter's display.
- Touch the probes to the indentations on either side of the resistance block special tool, and hold the probes vertically.
-
Verify that a resistance is
displayed.
NoteIf " -.- - - - " (no value) is displayed, check the lead connections to the resistance meter and the how the probe tips contact the resistance block.
-
Approximately 2 seconds
later, the resistance meter beeps and "0 ADJ" is now constant.
NoteIf "FAiL" is displayed, check the probe tips, the leads, and the connection to the resistance meter, and repeat from step #GUID-62BA0B0B-5667-4E7A-9377-FD16DF5909D4__GUID-A63E93E9-2C65-4CAA-9E7C-FAC8497DAA6F.
-
Remove the probes from the
resistance block special tool.
CAUTIONDo not change the range, otherwise the resistance meter must be zero adjusted again.
-
If necessary, unplug the Hioki 9461 test probe leads, and then plug the
3+1_point contactor probe leads into the resistance meter.
NoteAlign the arrows of the lead connectors to the arrows on the resistance meter.
- The resistance meter is now ready to measure resistance. Return to the procedure that required the zero adjust to be performed.
