4.
Select the desired temperature for calibration by clicking on the
thermometer graphic or selecting the temperature from the drop-
down box. Then click the
Calibrate
button to begin the calibration
for that temperature.
IMPORTANT NOTE
In each calibration session, the
initial
probe calibration must be per-
formed at 80°C (see procedure below) before calibrating at other tem-
peratures. When prompted by the VISCPRO software: "Do you want to
zero the offset at 80°C before calibrating?", click YES the first time in the
session that you attempt to calibrate at 80°C. Thereafter, click NO unless
you would like to start the calibration over from the default offset value.
The CMRV unit will begin heating or cooling to the desired tempera-
ture. When it reaches temperature, a 10-minute timer will start. This
delay allows the CMRV temperature to stabilize at the calibration
temperature. Note that more time may be required for stabilization at
80°C, 50°C and 0°C. After the timed delay, the
Thermometer
Temperature °C
field will become active, enabling data entry.

After the instrument reaches the probe calibration temperature and
completes the temperature stabilization period, type the actual
temperature from the reference thermometer in the
