Page 7: Introduction
1 Introduction Introduction Hart Scientific’s Model 9100 HDRC Dry-well Calibrator is a small, portable in- strument designed for quick on-site checks and calibration of thermocouple and RTD temperature probes. It features an aluminum temperature block well. Three different blocks are available. Block “A” has six holes, four that accept probe diameters of 1/4", 5/32", 1/8", and 1/16", and two that accept probes of...

Page 11: Safety Guidelines
3 Safety Guidelines Safety Guidelines • Operate the instrument in room temperatures between 5–40°C (41–104°F). Allow sufficient air circulation by leaving at least 6 inches of space between the instrument and nearby objects. Overhead clearance needs to allow for safe and easy insertion and removal of probes for cali- bration.

When the desired set-point temperature is reached, releasing button immediately changes the display back to the actual block temperature and the controller begins to heat or cool to the new set-point temperature. 9100 HDRC Figure 4. Front Panel 9100 Manual Rev. 8A1601...
Page 19: General Operation
6 General Operation General Operation Set-up Place the calibrator on a flat surface with at least 6 inches of free space in front of and behind the instrument. The prop may be swung down to raise the front of the instrument from a horizontal position. Plug the power cord into an AC grounded outlet of the appropriate voltage.
Page 21: Controller Operation
7 Controller Operation Controller Operation The controller is fully programmable. Each of the parameters such as propor- tional band, integration time, display units, and calibration offset can be viewed and altered. The controller has been configured at the factory for optimum ac- curacy, stability, and response time.

The controller may be locked again after changing parameters to avoid accidentally changing one of them. Follow the instructions above and replace the nOnE at the LoCK menu with ALL and then exit out of the program menu as explained.
Page 25: Test Probe Calibration
8 Test Probe Calibration Test Probe Calibration For optimum accuracy and stability, allow the calibrator to warm up for 10 min- utes after power-up and then allow adequate stabilization time after reaching the set-point temperature. After completing calibration, allow the block to cool before switching the power off.
Page 26: Calibration Of Multiple Probes
Inserting a cold probe into a well will require another period of stabilization de- pending on the magnitude of the disturbance and the required accuracy. For example, inserting a ¼ inch diameter probe at room temperature into a sleeve Manual Rev. 8A1601 Hart Scientific...
Page 27 8 Test Probe Calibration at 300°C will take approximately 5 minutes to be within 0.1°C of its set-point and will take 10 minutes to achieve maximum stability. Decreasing the time required for the calibration process can be accomplished by knowing how soon to make the measurement. It is recommended that typi- cal measurements be made at the desired temperatures with the desired test probes to establish these times.

Record the actual temperature of the dry-well. Repeat for set-points of 100°C, 150°C, 200°C, 250°C and 300°C. If any of the measured temperatures are not within specification, repeat the Span Adjust and the Zero Adjust section of the procedure as needed. Manual Rev. 8A1601 Hart Scientific...

Check that the power cord is plugged in. • If the unit has power and the display is off, the fuse may be blown and the unit needs to be returned to Hart Scientific for repair. Contact Hart Scien- tific Customer Service. The display flashes “Input Fail”...
Page 34: Ce Comments
• With the unit stable, slowly rotate the unit. If no change occurs, the unit may need to be calibrated. Contact Hart Scientific Customer Service. If the display changes more than twice the normal display deviation, another unit in the area could be emitting therefore energy. Move the unit to a differ- ent location and rotate the unit again.
