Multi-Turn Trim Pots
There are six 10K trim pots that are used for calibration of the Range Switch voltages.
Remember, if you are installing any of the variable range options, do not install
R41.
There are two 100K trim pots that are installed regardless of configuration.

Installing the ICS
All of the ICs are socketed, save for one – U5, the 78L10 Voltage Regulator. Locate its
position on the silk screening, and install it in the orientation depicted on the silkscreen of
the board.

After installing U5, all of the solder work is now done. Clean the board, then install the
rest of the ICs in their sockets. As a reminder, when handling the ICs, make sure you are
properly grounded to avoid damaging the ICs through electro-static discharge.
