1.2Safety Information

Use this instrument only as specified in this manual. Otherwise, the protection provided by the instrument may be impaired.

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 personal injury, follow these guidelines.

BURN HAZARD – DO NOT touch the well access surface of the unit. The temperature of the well access is the same as the actual temperature shown on the display. If the instrument is set at 140°C and the display reads 140°C, the well is at 140°C.

DO NOT remove inserts at high temperatures. Inserts are the same temperature as the display temperature. Use extreme care when removing hot inserts.

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 the power off and disconnect the power cord.

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

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

1 Before You Start

Authorized Service Centers

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 guide.

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.

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

•DO NOT use fluids to clean out the well.

•Never introduce 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 into 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

2Introduction

The Hart Scientific 9103 Dry-well may be used as a portable instrument or bench top temperature calibrator for calibration thermocouples and RTD temperature probes. The 9103 is small enough to use in the field and accurate enough to use in the lab. With an ambient temperature of 23°C (74°F), calibrations may be done over a range of –25°C to 140°C (–13°F to 284°F). The resolution of the 9103 temperature display is 0.1 degrees.

The calibrator features:

•Convenient handle

•RS-232 interface

•Universal AC input

Built in programmable features include:

•Temperature scan rate control

•Temperature switch hold

•Eight set-point memory

•Adjustable readout in °C or °F

The temperature is accurately controlled by Hart’s hybrid analog/digital controller. The controller uses a precision platinum RTD as a sensor and controls the well temperature with pulsed driven Thermal Electric Devices (TED).

The LED display panel 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 calibrator’s multiple fault protection devices insure user and instrument safety and protection.

The 9103 Dry-well was designed for portability, low cost, and ease of operation. Through proper use, the instrument will continuously provide 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 this user manual.
