Read First For Your Safety In case you use it in order to have you use it safely, be careful of the following things. Failure to observe the safety precautions can cause accidents that may damage the equipment or inflict injuries or death on the user or people around. DANGER 1. Avoid damaging cords and cables by leading them under the machine or getting them caught between objects. Otherwise the electric wire may short-circuit to cause electric shock, leak or fire. When disconnecting a cord or cable, be sure to do so by holding the plug or connector. Otherwise the cord or cable may have a break, which will eventually develop into functional failure, overheating or fire. 2. Be sure to use the charging AC adapter supplied with the equipment. Use of another AC adapter may not only lead to failure of the equipment but also cause fire or explosion due to abnormal heating. 3. Take special care during charging when both the equipment and the AC adapter heat up. Never place paper or cloth on the equipment and AC adapter during charging. To prevent fire, be sure to charge the equipment in a cool, well-ventilated place. WARNING 1. Give adequate care to safety in wiring the cables. Be sure to install them where they will not interfere with robot operation or the movement of workers. 2. Be sure to use the cables supplied with the equipment for connection with other equipment such as a printer. Otherwise faulty operation or functional failure may occur. 3. 4. For use and storage of this equipment, avoid locations where it can be exposed to sunshine, dust, rain water or excessive humidity. Place the equipment on a stable floor. Locating it at an elevated or unstable place can result in injuries from the drop of the equipment. 5. A battery pack should not carry out decomposition and reconstruction. If it decomposes and converts, it may generate heat, ignite or explode. 6. 7. Please do not add a strong shock to a battery pack. Moreover, please charge by the method of handling description specification. If a shock is added or it charges by methods other than specification, it may generate heat, ignite or explode. Please do not put in a battery pack into fire. If it puts in into fire or heats, it may explode or explode. 8. Changes or modifications not expressly approved by the manufacturer for compliance could void the user's authority to operate the equipment. 9. In order to comply with FCC radio-friquency radiation exposure guidelines for an uncontrolled exposure, this device and its antenna must not be co-located or operating in conjunction with any other antenna or transmitter. 10. The term "IC:" before the radio certification number only signifies that Industry Canada technical specifications were met.

"Operation of this device is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device."

"The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not emit RF field in excess of Health Canada limits for the general population; consult Safety Code 6, obtainable from Health Canada's website www.hc-sc.gc.ca/rpb"

Specification ........................................................................... 22 Outline 1. Outline 1 / 24 This machine is a welding current meter capable of measuring the welding current, welding cycle and tip voltage of resistance welders and displaying measured values on the liquid crystal display. The device presents the following features:

1) The equipment is small and lightweight, so that it can be easily carried around within the factory premises. 2) A large capacity memory allows storage of up to 10000 average data, 20 each cycle / each msec data and 1 newest waveform data. 3) Data is transmitted to a personal computer and data processing is possible with a personal computer.

(The exclusive software for personal computers is required) 4) Since the charge battery is built in, it is cordless and can be used. 5) Collection of the data in remoteness is possible by radio communications (Bluetooth). 6) The connectors for the cables used are all easy-to-use "one-touch" connectors. 7) There are two measuring ranges, namely, Lo:2.50 to 19.99kA and 10.00 to 49.99kA. You can select a range best suited to the current levels you are going to measure. 8) The WELD lamp lights up when welding is being detected. Therefore, measuring condition can be monitored even when you are away from the welding machine. 9) The equipment can be used not only with AC welder but also with DC welder, inverter controlled welder, and AC inverter controlled welder. 10) Current consumption is minimized by the auto power-off function, in which power is turned off automatically when there is no key operation, welding.

How to Charge 18 / 24 Attached AC adapter performs charge.

(1) Please connect attached AC adapter to a power supply jack, and check lighting of a CHARGE lamp.

(2) If it becomes -full charge, a CHARGE lamp will change to lighting slightly.

(3) A CHARGE lamp puts out the light by charge end. The maximum charge time is required for about 5 hours. Moreover, charge by USB bus power is also possible. Please connect a USB cable with a main part between PC. However, the software for PC is needed. Danger

- AC adapter for charge should surely use the thing of main part attachment. If other AC adapters are diverted, there are a fire not only by failure of a main part but unusual generation of heat and danger of a burst.

- A main part and AC adapter generate heat during charge. Be careful of handling enough. Moreover, covering paper and cloth during charge should stop. Please be sure to charge in a cool place with sufficient ventilation. It may become the cause of a fire.

- Even if it connects AC adapter for charge, when a CHARGE lamp does not light up, the defect of a battery pack is considered. Please stop use immediately. Caution

- Current cannot be measured when it is displayed on a liquid crystal display as

"LOW BATTERY" by drop in voltage of a battery. Please connect AC adapter immediately and charge a battery.

- If charge is completed, please remove AC adapter.

- After a "LOW BATTERY" display does not charge, and if a battery is exhausted further, a power source will be turn off automatically.

- A power source may be turn off before displaying "LOW BATTERY" depending on the state of a battery.

- If it is left where a battery is exhausted, all the saved data will be lost. When displayed as "LOW BATTERY", or when a power supply is automatically turn off by consumption, please charge immediately. Error Display 8.

Arithmetic means of effective value, effective value for each cycle, waveform of welding time, welding current, the tip voltage , and tip resistance are displayed as PDA or PC. 12. Auto-power-off After an external trigger and setting item change are lost, it is after 10 minutes, 30 minutes, and 60 minutes (selection). It power-supply-turns off. 13. Preservation of Measurement Data Measurement data is saved on the main part of a measuring instrument.
