Installation
The OHAUS Balance (GT8000) operates on 208Vac or
240Vac (full potential line voltage). The balance is config-
ured for supply voltage that corresponds with the NCAT
upon production at Barnstead International.
OHAUS balances were used in production from 1995 to
1998 and are currently sold as replacements only.
1. Ensure that both the balance and the furnace
are disconnected from the power supply.
Remove the four screws along the top of the
front control panel securing the control panel to
the lower case of the furnace.
2. Open the lower control panel by carefully swing-
ing the control panel down (hinged).
3. Inside the lower control assembly, observe the
suspended table supported by four aluminum
rods. The balance will be supported by this
table. Vacuum the table if dust, etc., appear on
it.
4. Mount the platform support plate on the bal-
ance. Note the four pins on the support plate.
These will retain the ceramic support tubes,
which will project into the furnace chamber after
mounting.
5. Orient the balance so that the front of the bal-
ance faces the back of the furnace. Run the
cable attached to the front of the balance under
the balance, so that the unattached end of the
cable emerges from beneath the back of the
balance.
6. Slide the balance front-first onto the suspended
table beneath the furnace chamber.
7. Position the balance so that the pins on the plat-
form support plate are directly beneath the four
tube ports in the bottom of the furnace chamber.
8. Plug the balance’s power cord (the black, three-
pronged female plug) into the socket on the rear
