Note(注释):

1.Prodigit has not fully transitioned to lead-free solder assembly at this moment；However, most of the

components used are RoHS compliant.

(此刻，Prodigit 并非完全过渡到无铅焊料组装；但是大部份的元器件一至于RoHS的规定。)

2. The product is labeled with an environment-friendly usage period in years.

The marked period is assumed under the operating environment specified in the product specifications.

(产品标注了环境友好的使用期限制(年)。所标注的环境使用期限假定是在此产品定义的使用环境之下。)

Example of a marking for a 10 year period:

(例如此标制环境使用期限为10年)

SAFETY SUMMARY

The following general safety precautions must be observed during all phases of operation, service,

and repair of this instrument. Failure to comply with these precautions or with specific warnings

elsewhere in this manual violates safety standards of design, manufacture, and intended use of the

instrument. PRODIGIT assumes no liability for the customer's failure to comply with these

requirements.

GENERAL

This product is a Safety Class 1 instrument (provided with a protective earth terminal). The protective

features of this product may be impaired if it is used in a manner not specified in the operation

instructions.

ENVIRONMENTAL CONDITIONS

This instrument is intended for indoor use in an installation category I, pollution degree 2 environments.

It is designed to operate at a maximum relative humidity of 80% and at altitudes of up to 2000 meters.

Refer to the specifications tables for the ac mains voltage requirements and ambient operating

temperature range.

BEFORE APPLYING POWER

Verify that the product is set to match the available line voltage and the correct fuse is installed.

GROUND THE INSTRUMENT

This product is a Safety Class 1 instrument (provided with a protective earth terminal). To minimize

shock hazard, the instrument chassis and cabinet must be connected to an electrical ground. The

instrument must be connected to the ac power supply mains through a three conductor

power cable, with the third wire firmly connected to an electrical ground (safety ground) at the power

outlet. Any interruption of the protective (grounding) conductor or disconnection of the protective earth

terminal will cause a potential shock hazard that could result in personal injury.

FUSES

Only fuses with the required rated current, voltage, and specified type (normal blow, time delay, etc.)

should be used. Do not use repaired

Fuses or short circuited fuse holder. To do so could cause a shock or fire hazard.

DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE.

Do not operate the instrument in the presence of flammable gases or fumes.

KEEP AWAY FROM LIVE CIRCUITS.

Operating personnel must not remove instrument covers. Component replacement and internal

adjustments must be made by qualified service personnel. Do not replace components with power

cable connected. Under certain conditions, dangerous voltages may exist even with the power cable

removed. To avoid injuries, always disconnect power, discharge circuits and remove external voltage

sources before touching components.

DO NOT SERVICE OR ADJUST ALONE.

Do not attempt internal service or adjustment unless another person, capable of rendering first aid and

resuscitation, is present.

DO NOT EXCEED INPUT RATINGS.

This instrument may be equipped with a line filter to reduce electromagnetic interference and must be

connected to a properly grounded receptacle to minimize electric shock hazard. Operation at line

voltages or frequencies in excess of those stated on the data plate may cause leakage currents in

excess of 5.0 mA peak.

DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT.

Because of the danger of introducing additional hazards, do not install substitute parts or perform any

unauthorized modification to the instrument. Return the instrument to a PRODIGIT ELECTRONICS

Sales and Service Office for service and repair to ensure that safety features

are maintained.

Instruments which appear damaged or defective should be made inoperative and secured against

unintended operation until they can be repaired by qualified service personnel.
