Safety Precautions

These products comply with the requirements of the following European Community Directives: 2004/108/EC (Electromagnetic Compatibility) and 2006/95/EC (Low Voltage) as amended by 2004/22/EC (CE-Marking); Overvoltage category II 300 V (P 4250); overvoltage category II 1000 V (P 4300); pollution degree 2.

CAT I: For signal level, telecommunication, electronic with small transient overvoltage
CAT II: For local level, appliances, main wall outlets, portable equipment
CAT III: Distribution level, fixed installation, with smaller transient overvoltage than CAT IV.
CAT IV: Units and installations, which are supplied overhead lines, which stand at a risk of persuading lightning, i.e. main switches on current input, overvoltage-diverter, and current use counter.

To ensure the safe operation of the equipment and eliminate the danger of serious injury due to short circuits (arcing), the following safety precautions must be observed.
Damages resulting from failure to observe these safety precautions are exempt from any legal claims.

• Do not clamp around conductors with voltages equal to or exceeding 1000 V DC or 750 V ACrms (P 4300) 300 V DC or 240 V ACrms (P 4250)
• To avoid physical injury, measurements on bare conductors or conductors with cracked or frayed insulators are forbidden
• Do not use these instruments for high-energy industrial installation measurement. These instruments are intended for use in installation overvoltage category II according to IEC 664.
• Check test leads and probes for faulty insulation or bare wires before connection to the equipment.
• To avoid electric shock, do not operate these products in wet or damp conditions. Conduct measuring works only in dry clothing and rubber shoes, i. e. on isolating mats.
• Comply with the warning labels and other info on the equipment.
• Always start with the highest measuring range when measuring unknown values.
•  Do not subject the equipment to direct sunlight or extreme temperatures, humidity, or dampness.
• Do not subject the equipment to shocks or strong vibrations.
• Do not operate the equipment near strong magnetic fields (motors, transformers, etc.).
• Keep hot soldering irons or guns away from the equipment.
• Allow the equipment to stabilize at room temperature before taking up measurements (important for exact measurements).
• Do not input values over the maximum range of each measurement to avoid damage of the meters.
• Replace the battery as soon as the battery indicator “LO BAT” appears. With a low battery, the meters might produce false readings that can lead to electric shock and personal injury.
• Fetch out the battery when the meters will not be used for a long period.
•  Periodically wipe the cabinets with a damp cloth and mild detergent. Do not use abrasives or solvents.
• The meters are suitable for indoor use only Do not operate the meter before the cabinet has been closed and screwed safely as the terminal can carry voltage.
• Do not store the meters in a place of explosive, inflammable substances.
• Do not modify the equipment in any way
• Opening the equipment and service – and repair work must only be performed by qualified service personnel
• Measuring instruments don’t belong to children’s hands

Cleaning the cabinet
Clean only with a damp, soft cloth and a commercially available mild household cleanser. Ensure that no water gets inside the equipment to prevent possible shorts and damage to the equipment.

General

The models PeakTech® 4250 or 4300 clamp adapters are transducers that will allow your multimeter to measure electrical current up to 1000 A (P 4300)/ 60 A (P 4250) AC or DC, with a frequency response up to 400 Hz (P 4300) / 20 kHz (P 4250). When measuring current with these clamp adaptors, there is no need to break a circuit or affect the insulation. These clamp adaptors are built with a design of finger guard which ensures user operating the lamp adaptors in a safety situation, with a rugged case that is
shock resistant and fire-retardant.

Application Procedures

P 4250:

1. Insert the black banana plug into the COM jack and the red banana plug into the V-Ω jack of any multimeter with a minimum input impedance of 10 kΩ.
2. Set the power switch from “OFF” to the desired range, 1 mV/10 mA or 1 mV/100 mA position. The green LED will light to indicate that the clamp is switched on.
3. For current measurements below 2 A, set the unit to 1 mV/10 mA range and set the multimeter to 200 mV AC range for AC current measurements, or 200 mV DC range for DC current measurements. If the measured current exceeds 2 A, set the unit 1 mV/100 mA range.
4. When performing DC current measurement, always push the zero adjustment button on the clam until the multimeter reads zero.
5. Clamp the jaws around the current-carrying conductor and interpret the reading according to step 3 above.
6. When 1 mV/10 mA range of clamp unit is selected, multiply the reading displayed on the multimeter by “10” for interpreting the measured current value in mA. For example, if the multimeter reads 10 mV, the measured current is 10 x 10 = 100 mA.

When 1 mV/100 mA range is selected, multiply the reading displayed on the multimeter by “100” for interpreting the measured current value in mA. For example, if the multimeter reads 5 mV, the measured current is 5 x 100 = 500 mA.
P 4300:

1. Insert the black banana plug into the COM-jack and the red banana plug into the V-Ω jack of any multimeter with a minimum input impedance of 1 MΩ.
2. Set the power switch from “OFF” to the desired range, 200 A or 1000 A position. The green LED will light to indicate that the clamp is switched on.
3. For current measurements below 200 amperes, set the unit to 200 A range and set the multimeter to 200 mV AC range for AC current measurements or 200 mV DC for DC current measurements. The reading in mV corresponds directly to A (for example 100mV ≙ 100A).
4. For current measurements above 200 amperes, set the unit to 1000 A range and set the multimeter range to 2 V AC or DC, depending on whether measuring AC or DC current. The reading is now amperes x 1000.
5. When performing DC current measurement, always push the zero adjustment button on the clamp until the multimeter reads zero.
6. Clamp the jaws around the current-carrying conductor and interpret the reading according to step 3 or 4 above.

Application notes

1. In the case of DC current, the output is positive when the current flows from the upside (marking “+” textured on the jaws) to the underside of the clamp. The red banana plug is positive.
2. In the case of DC current measurement, a hysteresis effect can occur so that it is impossible to zero the clamp properly. To eliminate this effect, open and close the jaws several times and push the zero adjustment button.

Battery Replacement

Remove the screw on the back side, open the case and remove the battery from the battery room, and replace it with a 9 V battery (NEDA 1604 type)
