1.1 Unpacking and Inspection

Every care is taken in the choice of packing material to ensure that your equipment will

reach you in perfect condition. If the equipment has been subject to excessive handling in

transit, the fact will probably be visible as external damage to the shipping carton.

In the event of damage, the shipping container and cushioning material should be kept for

the carrier’s inspection.

Carefully unpack the equipment and check for external damage to the standard. If the

shipping container and packing material are undamaged, they should be retained for use

in return shipments. If damage is found notify the carrier and Guildline immediately.

warranty period, will be repaired or replaced at our factory without charge at the discretion

of Guildline Instruments.

factory only after warranty authorization by the original manufacturer.

Limitation of Warranty

Warranty coverage does not apply to equipment which has failed due to misuse, neglect,

accident or abnormal conditions of operation or if modifications or repairs have been made

without prior written authorization of Guildline instruments.

Temperature probes are not warranted against failure due to mechanical shock.

Fuses, lamps and non-rechargeable batteries are not warranted against breakage.

Damage in Shipment to Orignal Purchase

Instrument(s) should be thoroughly inspected immediately on receipt for visible damage.

Any damage should be reported to the carrier and further inspection and operational tests

should be carried out if appropriate to determine if there is internal damage. Contact

Guildline Instruments before returning for repair. The Customer or purchaser must complete

all final claims with the carrier.

Regular charges will apply to non-warranty service. External service charges and expenses

will be billed at cost plus handling.

1.4 Safety Information

These Standards can be used with Equipment capable of voltages up to 1000 V. The

operator should be aware of the environment in which these standards are used.

WARNING: Use caution when working with voltages above 30 V ac rms, 42 V ac peak,

or 42 V dc. These voltages pose a shock hazard.

The 9334A Resistance Standards are designed to work within specifications to 100 mW of

power and 1000 Vdc or less. Applying more than the recommended power or voltage will

damage the unit and voids the warranty.

Do not use the Resistance Standard in wet environments.

Never use the Resistance Standard with the cover removed or the case open.

When making electrical connections, connect the common test lead before connecting the

live test lead; when disconnecting, disconnect the live test lead before disconnecting the

common test lead.

Inspect the Resistance Standard for damage such as cracked connectors prior to use. If unit

has a burned smell or smoke is visible during use, discontinue use immediately.

If test equipment used with Resistance standards overloads or trips, this could be a sign that

the resistance standard requires repair..

Inspect all test leads used with the Resistance Standard for damaged insulation or exposed

metal. Check all test leads for continuity.

Ensure all test leads are correctly connected prior to applying current or voltage.

Do not use resistance standards around explosive gas, vapor or dust.
