1.2Safety Information

Use the instrument only as specified in this manual. Otherwise, the protection provided by the instrument may be impaired. Refer to the safety information below and throughout the manual.

The following definitions apply to the terms “Warning” and “Caution”.

“Warning” identifies conditions and actions that may pose hazards to the user.

“Caution” identifies conditions and actions that may damage the instrument being used.

1.2.1

Warnings

To avoid possible electric shock or personal injury, follow these guidelines.

BURN HAZARD Do Not touch the well access surface of the unit.

(Refer to Figure 1 on page 3.)

The temperature of the well access (1) will be the same as the actual temperature shown on the display (2), e.g. if the unit is set at 600°C and the display reads 600°C, the well is at 600°C.

The top sheet metal (3) of the dry-well may exhibit extreme temperatures for areas close to the well access.

The air over the well can reach temperatures greater than 200°C.

PROBES SHOULD ONLY BE INSERTED AND REMOVED FROM THE UNIT WHEN THE UNIT IS SET AT TEMPERATURES LESS THAN 200°C.

DO NOT TURN OFF THE UNIT AT TEMPERATURES HIGHER THAN 100°C. This could create a hazardous situation. Select a set-point less than 100°C and allow the unit to cool before turning it off.

DO NOT operate this unit without a properly grounded, properly polarized power cord.

DO NOT connect this unit to a non-grounded, non-polarized outlet.

HIGH VOLTAGE is used in the operation of this equipment. SEVERE INJURY OR DEATH may result if personnel fail to observe safety precautions. Before working inside the equipment, turn power off and disconnect power cord.

Always replace the fuse with one of the same rating, voltage, and type.

Overhead clearance is required. DO NOT place unit under a cabinet or other structure.

DO NOT use this unit for any application other than calibration work.

DO NOT use this unit in environments other than those listed in the user’s manual.

DO NOT turn the unit upside down with the inserts in place; the inserts will fall out of the unit.

DO NOT operate near flammable materials.

Use of this instrument at HIGH TEMPERATURES for extended periods of time requires caution.

Completely unattended high temperature operation is not recommended for safety reasons.

Before initial use, after transport and anytime the dry-well has not been energized for more than 10 days, the calibrator must be energized for a dry-out period of 1 to 2 hours before it can be assumed to meet all of the safety requirements of the IEC1010-1.

Follow all safety guidelines listed in the user’s manual.

CALIBRATION EQUIPMENT should only be used by TRAINED PERSONNEL.

1.2.2

Cautions

To avoid possible damage to the instrument, follow these guidelines.

Components and heater lifetime can be shortened by continuous high temperature operation.

1 Before You Start

Components and heater lifetime can be shortened by continuous high temperature operation.

Most probes have handle temperature limits. Be sure that the probe handle temperature limit is not exceeded in the air above the unit.

(9107 only) Always use the well insulator, see Section 5.4.

Allow for test probe expansion inside the well as the dry-well heats.

DO NOT use fluids to clean out the well.

Never introduce any foreign material into the probe hole of the insert. Fluids, etc. can leak into the calibrator causing damage.

DO NOT change the values of the calibration constants from the factory set values. The correct setting of these parameters is important to the safety and proper operation of the calibrator.

DO NOT slam the probe stems in to the well. This type of action can cause a shock to the sensor and affect the calibration.

DO use a ground fault interrupt device.

2 Introduction

2 Introduction

The Hart Scientific Model 9105/9107 dry-well calibrator may be used as a portable instrument for calibration of temperature probes. The 9105 operates over the range of –25°C and 140°C. The 9107 operates over the range of –45°C to 140°C.

These dry-well calibrators feature an interchangeable aluminum probe sleeve along with 4 fixed wells. The temperature is accurately controlled by Hart's precision temperature controller.

The calibrator controller uses a precision platinum RTD as a sensor and controls the well temperature with thermoelectric modules. The LED front panel display continuously shows the current well temperature. The temperature may be easily set with the control buttons to any desired temperature within the specified range.

The 9105/9107 dry-well calibrator was designed for portability, moderate cost, and ease of operation. With proper use the instrument should provide continued accurate calibration of temperature sensors and devices. The user should be familiar with the safety guidelines and operating procedures of the calibrator as described in the User’s Guide.

4 Safety Guidelines

4Safety Guidelines

Operate the instrument in room temperatures between 5–50°C (41–122°F). Allow sufficient air circulation by leaving at least 6 inches of space between the instrument and nearby objects. DO NOT place under a cabinet or other structure. Allow for overhead clearance.

The dry-well is a precision instrument. Although it has been designed for optimum durability and trouble free operation, it must be handled with care. Always carry the unit in an upright position to prevent the probe sleeves from dropping out. The convenient fold-up handle allows one hand carrying. The instrument should not be operated in excessively wet, oily, dusty, or dirty environments. It is important to keep the well of the instrument clean and clear of any foreign matter. DO NOT operate near flammable materials.

DO NOT use fluids to clean out the well.

The instrument can generate extreme temperatures. Precautions must be taken to prevent personal injury or damage to objects. Probes may be extremely hot or cold when removed from the instrument. Cautiously handle probes to prevent personal injury. Always use the special sleeve tongs that are supplied with the calibrator to remove the sleeve. Carefully place probes on a heat/cold resistant surface or rack until they are at room temperature. Never place any objects other than the special probe sleeves supplied with the calibrator into the well.

Use only a grounded AC mains supply of the appropriate voltage to power the instrument. The Model 9105 dry-well requires 3 amps SB at 115 VAC (±10%), 50/60 Hz, 1.6 amps T at 230 VAC (±10%). The Model 9107 dry-well requires 4 amps SB at 115 VAC (±10%), 50/60 Hz, 3.15 amps T at 230 VAC (±10%).

Before initial use, after transport, and anytime the dry-well has not been energized for more than 10 days, the instrument needs to be energized for a “dry-out” period of 1-2 hours before it can be assumed to meet all of the safety requirements of the IEC 1010-1.

The instrument is equipped with operator accessible fuses. If a fuse blows, it may be due to a power surge or failure of a component. Replace the fuse once. If the fuse blows a second time, it is likely caused by failure of a component part. If this occurs, contact Hart Scientific Customer Service. Always replace the fuse with one of the same rating, voltage, and type. Never replace the fuse with one of a higher current rating.

If a mains supply power fluctuation occurs, immediately turn off the instrument. Power bumps from brown-outs and black-outs could damage

5 Quick Start

5 Quick Start

5.1Unpacking

Unpack the dry-well carefully and inspect it for any damage that may have occurred during shipment. If there is shipping damage, notify the carrier immediately.

Verify that the following components are present:

9105 or 9107 Dry-well

2173 Insert, 1/4” Aluminum

Power Cord

Manual

Two Well Insulators (9107 only)

Tongs (insert removal tool)

5.2Set-up

Place the calibrator on a flat surface with at least 6 inches of free space around the instrument. Overhead clearance is required. DO NOT place under a cabinet or structure. Plug the power cord into a grounded mains outlet. Observe that the nominal voltage corresponds to that indicated on the back of the calibrator.

Carefully insert the probe sleeve into the well. Probe sleeves should be of the smallest hole diameter possible still allowing the probe to slide in and out easily. Sleeves of various sizes are available for Hart Scientific. The well must be clear of any foreign objects, dirt and grit before the sleeve is inserted. The sleeve is inserted with the two small tong holes positioned upward.

Turn on the power to the calibrator by toggling the switch on the power entry module. The fan should begin quietly blowing air through the instrument and the controller display should illuminate after 3 seconds. After a brief self-test the controller should begin normal operation. If the unit fails to operate please check the power connection.

The display will begin to show the well temperature and the well heater will start operating to bring the temperature of the well to the set-point temperature.

5.3Power

Plug the dry-well power cord into a mains outlet of the proper voltage, frequency, and current capability. Typically this will be 115 VAC (±10%), 50/60 Hz (230 VAC ±10%, 50/60 Hz). Turn the dry-well on using the rear panel

9105/9107

5 Quick Start

“POWER” switch. The dry-well will turn on and begin to heat to the previously programmed temperature set-point. The front panel LED display will indicate the actual dry-well temperature.

The 9107 is field switchable between 115 V and 230 V. Refer to Section 7.2, Switching to 230 V Operation, for information on switching the voltage.

5.4Setting the Temperature

Section 8.3 explains in detail how to set the temperature set-point on the calibrator using the front panel keys. The procedure is summarized here.

1.Press “SET” twice to access the set-point value.

2.Press “UP” or “DOWN” to change the set-point value.

3.Press “SET” to program in the new set-point.

4.Press “EXIT” to return to the temperature display.

When the set-point temperature is changed the controller will switch the well heater on or off to raise or lower the temperature. The displayed well temperature will gradually change until it reaches the set-point temperature. The well may require 5 to 10 minutes to reach the set-point depending on the span. Another 5 to 10 minutes is required to stabilize with ±0.1°C of the set-point. Ultimate stability may take 15 to 20 minutes more of stabilization time.
