SmartReader Plus Data Logger

For the internal channel, use equation 45

For the 100 ohm probes, use equation 86

For the 1000 ohm probes, use equation 87

For results in resistance (ohms):

For the internal channel, use equation 45

For the 100 ohm probes, use equation 84

For the 1000 ohm probes, use equation 85

NOTE: Even equation numbers are for 100 W probes and odd equation

numbers are for 1000 W probes.

4. Adjust the remaining setup options as desired then save the setup.
