1.2 Working Condition

1.2.1 Power Connection

1) Power supply: 100~120Vac or 198~242Vac

2) Power supply frequencies: 47~63Hz

3) Power range: ≥80VA

4) The power input line L, zero-line N and ground-line E should be the same as the power plug of this

instrument. Remove the protection cover on the rear panel before use of the instrument, the detailed

wire connection diagram is shown in figure 1-1:

Figure 1-1

1.2.2 Environment Temperature and humidity

TH7100 series programmable AC power supply is only allowed to be used indoors and in low-condensation

areas. The general environmental requirements of this instrument are shown in table 1-2. The fan speed changes

intelligently with the radiator temperature. When the radiator temperature reaches 60°C, the fan accelerates.

When the radiator temperature reaches 130°C, the instrument shuts off the output.

1.2.3 Precautions for usage

1) Please do not use the tester in dusty, vibrative, direct sunlight and corrosive gases and other adverse

environments.

2) Please do not use damaged equipment. Before use of the instrument, please check if there are any

cracks on the shell.

3) Please connect the device with the provided cable. Before operating the instrument, make sure theAC

power supply is well grounded.

4) Before connecting to the device, check all the security labels on the device.

5) Please use wire with rated load. The capacity of all load wires must be able to withstand the maximum

short-circuit output current of the power supply without overheating. If there are multiple loads, each

pair of load wires must be able to safely carry the full load rated short-circuit output current of the

power supply.

6) Please do not install replacement parts or make any unauthorized modification of the instrument.

7) Please do not use the device when the cover is removed or loose.

8) It is strictly prohibited to use this instrument on life support system or any other equipment with safety

requirements.

9) Keep the instrument well ventilated to avoid overheating. Do not block the ventilation hole of the

equipment to avoid internal temperature rising affecting the accuracy.

10) Please use dry cloth to clean the shell of the equipment. Do not clean the inside of the instrument.

11) Please do not switch the instrument frequently to avoid loss of stored data.

12) The instrument has been carefully designed to reduce clutter due to AC power input. However, it

should still be used under low noise conditions. If that is inevitable, please install the power filter.

13) When the instrument is not used for a long time, please put it in the original box or similar box and

stored in a ventilated room with temperature of 5℃~40℃and relative humidity less than 85% RH.

Do not store the instrument in a corrosive atmosphere containing harmful impurities and should avoid

direct sunlight.

1.2.4 Warm-up

For accurate measurement, the warm-up time should not be less than 30 minutes.

1.3.2 Laws and regulations

CE label indicates that the instrument complies with all relevant European laws (a year indicates the

year in which the design was approved).

This device complies with the marking requirements of WEEE directive (2002/96/EC), and this

additional product label states that this appliance/electronic product should not be discarded in household waste.
