Fitting the end clamps
The end clamp kit is designed to be used with the RKLC40-S scale to ensure the scale is
mastered to the substrate.
NOTE: The end clamps can be mounted before or after readhead installation.
1. Clean both ends of the scale and the area where the end clamps are to be fitted
using Renishaw scale wipes or one of the recommended solvents
(see
'Storage and handling'
on page 9).
2. Thoroughly mix up a sachet of RGG-2 two-part epoxy adhesive and apply a small amount to
the underside of the end clamp.

To ensure scale end movement of typically < 1 μm, stabilise the system at least 5 °C higher than the maximum customer application temperature for a minimum of 8 hours. For example: Customer application = 23 °C axis
temperature. Stabilise the system at 28 °C for a minimum of 8 hours.

3. The end clamp features two small regions of contact adhesive. These will temporarily hold the
end clamp in position while the epoxy cures. Remove the backing tape from either side.
4. Immediately position the end clamp over the end of the scale and push down to ensure
complete adhesion. Allow 24 hours at 20 °C for a full cure.
CAUTION: Ensure that excess epoxy is wiped away from the scale as it may affect the readhead
signal level.
