1.2 Safety 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 in-

strument being used.

1.2.1 WARNINGS

To avoid personal injury, follow these guidelines.

•Before initial use, or after transport, or after storage in humid or semi-hu-

mid environments, or anytime the instrument has not been energized for

more than 10 days, the instrument needs to be energized for a “dry-out”

period of 2 hours before it can be assumed to meet all of the safety re-

quirements of the IEC 1010-1. If the product is wet or has been in a wet

environment, take necessary measures to remove moisture prior to apply-

ing power such as storage in a low humidity temperature chamber operat-

ing at 50 degree centigrade for 4 hours or more.

•Use only a grounded AC mains supply of the appropriate voltage to

power the instrument. The dry-well requires a maximum of 1 amp, 50/60

Hz, 115/230 VAC (±10%).

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

•DO use a ground fault interrupt device.

•HIGH VOLTAGE is used in the operation of this equipment. SEVERE

INJURY or DEATH may result if personnel fail to observe safety pre-

cautions. Before working inside the equipment, turn power off and dis-

connect power cord.

9101 Zero Point Dry-Well

User’s Guide

•DO NOT use this unit in environments other than those listed in the

user’s manual.

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

•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.

•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 be-

tween the instrument and nearby objects. Overhead clearance needs to al-

low for safe and easy insertion and removal of probes for calibration.

•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. The instrument should not be operated in excessively wet, oily,

dusty, or dirty environments. It is important to keep the wells of the in-

strument clean and clear of any foreign matter. Do not operate near flam-

mable materials.

•DO NOT use fluids to clean out the well.

•If a mains supply power fluctuation occurs, immediately turn off the in-

strument. Power bumps from brown-outs and black-outs could damage

the instrument. Wait until the power has stabilized before re-energizing

the instrument.

9101 Zero Point Dry-Well

User’s Guide

2 Introduction

The Hart model 9101 zero point dry-well is a precision instrument which main-

tains a constant temperature at 0°C. It can be used to provide a stable zero ref-

erence for thermocouples or for calibrating temperature probes.The 9101 has

three wells so that multiple probes may be calibrated and compared at once.

The 9101 uses solid-state electronics to control the temperature of an aluminum

block. The block temperature is monitored with a high sensitivity thermistor

sensor. The controlling circuit adjusts the current to thermoelectric modules

which cool the block maintaining a stable temperature. Since the current to the

cooling modules is constant DC there is no problem with induced EMF noise in

the user’s probes or thermocouples due to switching transients of the cooling

circuits. Because the temperature control is done with solid-state electronics the

9101 is rugged and stable. The zero point dry-well will not be damaged by

subfreezing temperatures during shipping or storage.

The 9101 is calibrated at the factory for NIST traceable accuracy. It may also

be easily calibrated in the field to the user’s own standard.

•temperature range: 5–50°C (41–122°F)

•ambient relative humidity: maximum 80% for temperature <31°C, de-

creasing linearly to 50% at 40°C

•pressure: 75kPa–106kPa

•mains voltage within ±10% of nominal

•vibrations in the calibration environment should be minimized

•altitude does not effect the performance or safety of the unit
