Calibration Procedure for UL Adapter
When a UL Adapter is used, the water bath is stabilized at the proper temperature:
1) Put the proper amount of viscosity standard fluid into the UL Tube. (Refer to the UL
Adapter instruction manual).
2) Attach the spindle (with extension link and coupling nut) onto the DV-I+.
3) Attach the tube to the mounting channel.
4) Lower the tube into the water bath reservoir, or if using the ULA-40Y water jacket, connect
the inlet/outlets to the bath external circulating pump.
5) Allow sufficient time for the viscosity standard, sample chamber and spindle to reach test
temperature.
6) Measure the viscosity and record the viscometer reading; include % and cP (m•Pas).
NOTE: The spindle must rotate at least five (5) times before a viscosity reading is
taken.
Calibration Procedure for DIN Adapter
When a DIN UL Adapter is used, the water bath is stabilized at the proper temperature:
1) Put the proper amount of viscosity standard fluid into the UL Tube. (Refer to the UL
Adapter instruction manual).
2) Attach the spindle (with extension link and coupling nut) onto the DV-I+.
3) Attach the tube to the mounting channel.
4) Lower the tube into the water bath reservoir, or if using the ULA-40Y water jacket, connect
the inlet/outlets to the bath external circulating pump.
5) Allow sufficient time for the viscosity standard, sample chamber and spindle to reach test
temperature.
6) Measure the viscosity and record the viscometer reading; include % and cP (m•Pas).
NOTE: The spindle must rotate at least five (5) times before a viscosity reading is taken.
