Limited Warranty & Limitation of Liability

Each product from Fluke's Hart Scientific Division ("Hart") is warranted to be free from defects in mate rial and workmanship under normal use and service. The warranty period is three years for the Thermom eter Readout. The warranty period begins on the date of the shipment. Parts, product repairs, and services are warranted for 90 days. The warranty extends only to the original buyer or end-user customer of a Hart authorized reseller, and does not apply to fuses, disposable batteries or to any other product which, in Hart's opinion, has been misused, altered, neglected, or damaged by accident or abnormal conditions of operation or handling. Hart warrants that software will operate substantially in accordance with its func tional specifications for 90 days and that it has been properly recorded on non-defective media. Hart does not warrant that software will be error free or operate without interruption. Hart does not warrant calibra tions on Thermometer Readouts.

Hart authorized resellers shall extend this warranty on new and unused products to end-user customers only but have no authority to extend a greater or different warranty on behalf of Hart. Warranty support is available if product is purchased through a Hart authorized sales outlet or Buyer has paid the applicable international price. Hart reserves the right to invoice Buyer for importation costs of repairs/replacement parts when product purchased in one country is submitted for repair in another country.

Hart's warranty obligation is limited, at Hart's option, to refund of the purchase price, free of charge re pair, or replacement of a defective product which is returned to a Hart authorized service center within the warranty period.

To obtain warranty service, contact your nearest Hart authorized service center or send the product, with a description of the difficulty, postage, and insurance prepaid (FOB Destination), to the nearest Hart authorized service center. Hart assumes no risk for damage in transit. Following warranty repair, the product will be returned to Buyer, transportation prepaid (FOB Destination). If Hart determines that the failure was caused by misuse, alteration, accident or abnormal condition or operation or handling, Hart will provide an estimate or repair costs and obtain authorization before commencing the work. Following repair, the product will be returned to the Buyer transportation prepaid and the Buyer will be billed for the repair and return transportation charges (FOB Shipping Point).

1.2 Safety Information

Use this instrument only as specified in this manual. Otherwise, the protection provided by the instrument may be impaired. Refer to the safety information in Sections 1.2.1 and 1.2.2.

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 instru-

ment being used.

1.2.1 Warnings

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

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.

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 use this instrument in combination with any probe to measure the temperature or resistance of any device where the probe might come in contact with a conductor that is electrically energized. Severe electric shock, personal injury, or death may occur.

If this equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

1 Before You Start

Safety Information

Before initial use, or after transport, or after storage in humid or semi-humid 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 requirements 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 applying power such as storage in a low humidity temperature chamber operating at 50°C for 4 hours or more.

The AC adapter can present safety concerns if misused or damaged. To avoid the risk of electric shock or fire, do not use the AC adapter outdoors or in a dusty, dirty, or wet environment. If the cord, case, or plug of the adapter is damaged in any way, discontinue its use immediately and have it replaced. Never disassemble the AC adapter. Use only the AC adapter provided with the instrument or equivalent adapter recommended by the manufacturer of this instrument.

Follow all safety guidelines listed in this user's guide.

Calibration Equipment should only be used by Trained Personnel.

To avoid possible burn hazards, follow these guidelines.

This instrument can measure extreme temperatures. Precautions must be taken to prevent personal injury or damage to objects. Probes may be extremely hot or cold. Cautiously handle probes to prevent personal injury. Carefully place probes on a heat/cold resistant surface or rack until they reach room temperature.

DC Battery Pack Option: To avoid possible safety hazards, follow these guidelines:

To avoid the risk of electric shock or fire, DO NOT use the charger outdoors or in a dusty, dirty, or wet environment.

If the cord, case, or plug of the charger is damaged in any way, discontinue its use immediately and have it replaced.

Never disassemble the charger.

The battery may contain chemicals that are hazardous. To avoid the risk of ex

posure to dangerous substances or explosion, immediately discontinue use of the battery if it leaks or becomes damaged.

Never allow the battery to be shorted, heated, punctured, dropped, or squashed.

Store the battery where it will not come in contact with metal or fluids that might short circuit the battery and where it will be safe from excessive temperatures.

When no longer usable, the battery must be recycled. The battery may be re

turned to the seller for recycling. DO NOT dispose of the battery in a landfill. Never dispose of the battery in a fire as there is a danger of explosion which may cause injury or property damage..

1.2.2

Cautions

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

DO NOT change the values of the calibration constants from the factory set

values unless you are recalibrating the instrument. The correct setting of these parameters is important to the safety and proper operation of the instrument.

Allow sufficient air circulation by leaving at least 3 inches of space between the thermometer and nearby objects.

For CE compliance and for performance, use only the AC adapter shipped with the instrument by Hart Scientific. If the AC adapter needs to be replaced, con tact your an Authorized Service Center.

This instrument and thermometer probes are sensitive and can be easily dam aged. Always handle these devices with care. DO NOT allow them to be dropped, struck, stressed, or overheated.

Probes are fragile instruments which can be damaged by mechanical shock, over-heating, and absorption of moisture or fluids in the wires or hub. Damage may not be visibly apparent but nevertheless can cause drift, instability, and loss of accuracy. Observe the following precautions:

DO NOT allow probes to be dropped, struck, bent, or stressed.

DO NOT overheat probes beyond their recommended temperature range.

DO NOT allow any part of the probe other than the sheath to be immersed in fluid.

DO NOT allow the probe hub or wires to be exposed to excessive temperatures.

Keep the probe wires clean and away from fluids.

DC Battery Pack Option:

If the battery charge is not sufficient (less 10.25V), the instrument will continue to function while taking incorrect measurements. DO NOT utilize the instru ment for measuring when the Low Voltage Indicator is lit.
