reduced proportionally. The resolution of the module in current mode is 20,000 different current
levels spread over the 0 – 20mA current range; when the current output range is reduced (e.g. 4 –
20mA) the number of different current levels will be reduced proportionally.
Reverse Scaling:
The output can be set up as reverse acting if desired. By reverse acting, the voltage or current
output will decrease as the temperature increases. To set up the analog output in reverse acting
mode, assign the minimum voltage or current to the maximum temperature and assign the
maximum voltage or current to the minimum temperature.
Calibration:
Checking Calibration of Analog Output Module:
Calibration of the analog output is very easy and straightforward. A menu within TemperaSure
provides an easy-to-use interface for the calibration of the analog output. Checking the
calibration does not affect the calibration Analog Output Module. To check the calibration,
follow the steps below. Instructions for changing the calibration follow this section. Calibration
of the analog output is not be required before the first year of operation and only annually after
the first year.
To check the calibration of the Analog Output Module:
1. Make sure that the Analog Output Module and the probe are disconnected from any process,
system, or tool that could be affected by readings from the Analog Output Module or the
probe itself.
2. Verify that the voltage or current meter being used to calibrate the Analog Output Module is
properly calibrated and its calibration is up to date.
3. Connect the probe to a computer capable of running the TemperaSure software under the
Windows

operating system. Open the TemperaSure software and verify readings are
coming from the probe to the computer.
4. Connect the meter to the Analog Output Module. If the Analog Output Module is to be used
in voltage mode, the meter should be connected in parallel with the output. If the Analog
Output Module is to be used in current mode, the meter should be connected in series.
5. Configure the Analog Output Module for Internal Power (see instructions for Optional
External Power).
6. Make sure the Analog Output Module has been running for at least 30 minutes so it is fully
warmed up.
7. Determine the COM port to which the probe is connected. To determine the COM port, click
on the numbered box above the temperature readout for the probe. The COM port will be
displayed in the Probe section on the General tab.
8. Under the Options menu in TemperaSure, select Analog Calibration. A calibration menu box
will pop up (see Figure A-18).
9. Using the menu, select the COM port of the probe that is attached to the Analog Output
Module and whether the Analog Output Module is being used in voltage or current mode.
