Kistler-Morse KM Microcell Bolt-On - Manual (Page 8)

A. Proceed to TESTING WITH A DIGITAL
MULTIMETER (DMM) to determine the
resistance values for that Microcell™,
and
B. Contact Kistler-Morse ® for assistance
after determining the resistance values
and before proceeding with installation.
CAUTION
Replace Micrcells™ in packing tubes until ready
to install.

TESTING WITH A DIGITAL MULTIMETER (DMM)
Follow this procedure to test the Microcell™ sets
if you do not have a Kistler-Morse
® Test Meter or
the readings using the Test Meter were outside the
specifications:
1. Set the DMM resistance scale to
accommodate a measured range up to
20,000Ω.
2. Put one DMM lead on the Microcell™ white
wire and the other lead on the red wire. Place
the Microcell™ on a stable surface. Verify the
resistance is within the following limits:
3” standardized Microcell™ (light blue cover):
8,300Ω - 8,700Ω
2” standardized Microcell™ (dark blue cover):
1,800Ω - 2,200Ω
3. Put one DMM lead on the Microcell™ white
wire and the other lead on the black wire.
Place the Microcell™ on a stable surface.
Verify the resistance is within the following
limits:
3” standardized Microcell™ (light blue cover):
8,300Ω - 8,700Ω
2” standardized Microcell™ (dark blue cover):
1,800Ω - 2,200Ω
4. Repeat Steps 2 and 3 for each Microcell™. If
either reading for any Microcell™ is outside
these specifications, contact Kistler-Morse ® for
assistance before proceeding with installation.
CAUTION
Replace Micrcells™ in packing tubes until ready
to install.
