Note: When using the Ohaus External Temperature Probe, the temperature
setpoint should be adjusted to the desired sample temperature. If the
temperature setpoint is higher than the sample can achieve, an E7 will occur
(see the Troubleshooting section). Reduce sample volume or temperature
setpoint value. For Example: Water has a theoretical temperature limit of
100° C (boiling). A temperature setpoint greater than 100° C will cause an E7
error.
