Installing the Secure
Memory Module
Step 1. When replacing an HI 2160RC
PLUS
controller or adding a con-
troller with the same operating parameters, transferring the
Secure Memory Module (SMM) from the existing controller
is a fast way to calibrate and setup a new instrument. The user
should make a back up SMM when setting the operating
parameters for the original equipment.
Step 2. Make sure that the module has the notch facing up. (See Fig.
3-35)
Step 3. Slide the module with the notch up into the module housing.
Step 4. Press the module in until it stops.
Step 5. To remove the module pull the module straight out of the
housing. (See Fig. 3-36)
