• Replace a defective fuse only with a fuse of the original rating.
• Never short-circuit fuse or fuse holding.
• Check test leads and probes for faulty insulation or bare wires before connection to the equipment.
• Never touch the tips of the test leads or probe.
• Comply with the warning labels and other info on the equipment.
• 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 measurement (important for exact measurements).
• Periodically wipe the cabinet with a damp cloth and mid detergent.
• Do not use abrasives or solvents.
• The device is suitable for indoor use only
• Do not operate the meter before the cabinet has been closed and screwed safely as terminal can carry voltage.
• Do not store the meter in a place of explosive, inflammable substances.
• Do not modify the equipment in any way
• Do not place the equipment face-down on any table or work bench to prevent damaging the controls at the front.
• Opening the equipment and service  and repair work must only be performed by qualified service personnel
• Laboratory power supplies are no battery chargers and do not have a special protection against reverse voltage and false polarity.
• Do not use for charging batteries!
• Do not operate the device to power inductive loads, such as electric motors, which act as a generator during overrun and thus can produce a reverse voltage.
• Measuring instruments don’t belong to children hands.

Cleaning the cabinet

Prior to cleaning the cabinet, withdraw the mains plug from the power outlet. 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.

Operating method

Setting the constant voltage output:

Set the desired output voltage with the voltage knob (3). Press on the voltage knob, to select the desired digital point for coarse or fine adjustment. Once the desired voltage is set, turn on the output with the Output button (8). The C.V. and Output-LED indicates the voltage output.

Current limitation / constant current output

Set the desired current limitation when output is off with the current knob 4. Press the current knob to select the desired digital point for coarse or fine adjustment. Once the desired current is set, turn on the output with the Output button 8. The C.C. and output LEDs indicate an active current limitation.

Note
The maximum output current is determined by the connected load. You can’t charge a connected consumer with a higher power than it actually needs.

PeakTech 6226

In current setting values under 9.9 A, the display will show X.XXX 1 mA resolution when setting value reach or over 9.9 A the display will show XX.XX 10mA resolution.

Activate / deactivate key lock

Once you have adjusted the desired settings, press and hold the voltage and current controls for 3 seconds to activate a key lock. Now only the output button is operable, but the voltage and current control can’t be changed. Press both buttons again for 3 seconds to disable the key lock

Note
If the power supply cannot be turned on and the mains supply is turned on, the fuse of the laboratory power supply maybe triggered. Turn on the laboratory power supply, unplug the power cord and replace the fuse. Does the replacement of the fuse is not successful, maybe a defective in the device can be present. Consult your dealer to carry out an inspection. If the output voltage in constant voltage mode is lower than the preset voltage and the CC indicator lights, the power supply has automatically switched to the constant current mode. Check the connected load or increase the output current. If the output current in constant current mode is lower than the preset current and the CV indicator lights, the power supply has automatically switched to the constant voltage mode. Check the connected load or increase the output voltage. If the output voltage in constant voltage operation is not stable or jumps, it is probably the mains supply voltage drops below 90% of the rated value. If the problem is not caused by the mains supply voltage, contact your dealer.

Caution
The mains power must be switched off before servicing and servicing should be referred to a qualified person. The unit should be stored in a dry and well ventilated place and the power cord removed if storing for long periods. Laboratory Power Supplies are not designed for charging batteries. Any use of this type can cause serious damage to the device, which are exempt from any legal claims whatever. Do not operate the device to power inductive loads, such as electric motors, which act as generator during overrun and thus can produce a reverse voltage. Replace fuse only with an identical fuse.
