The multifunctional tool is designed for crimping, cutting, and stripping cables, as well as shortening screws. Made of high-quality metal, this versatile tool fits easily in your pocket and is the perfect companion for any DIY project - from workshop tasks to automotive repairs, model making, and electrical installations.

• Crimping capacity for insulated cable lugs, connectors, heat shrink connectors, wire end sleeves, and flat plug sleeves with cross-sections of 1.25 mm² (red), 2.0 mm² (blue), and 5.5 mm² (yellow)
• Color-coded jaws for easy and precise crimping of different diameters
• Suitable for crimping uninsulated open connectors with cross-sections of 1.25 mm², 2.0 mm², and 3.5-5.5 mm², such as MC4 connectors on solar cables
• Integrated threaded holes enable precise cutting of copper or brass screws and threaded pins (M 2.6, M 3, M 3.5, M 4, M 5)
• Robust metal blade cleanly cuts wires and cables up to 6.0 mm² in thickness
• Precision openings for cable cross-sections of 0.75 mm², 0.9 mm², 1.25 mm², 2.0 mm², 3.5 mm², and 5.5 mm² prevent damage to individual strands during stripping
• Stripping tool compatible with standard insulation materials and solid wires in AWG sizes 10-20

Kit of a bias probe for indirect measurement of the quiescent bias current of a tube. The adapter is placed between the tube and the socket and is connected to a standard voltmeter (not included). Pay attention to the quality of the meter and to sufficiently charged batteries!

The quiescent current is measured indirectly via a precision resistor built into the adapter. The advantages of this measuring method are harmless voltages in the mV range at the measuring plugs as well as short ways for the current, since it does not have to be led through the measuring device (common practice with many measuring adapters of Far Eastern production). As a result, there is no risk of oscillation of the amplifier, which could damage the tubes or the amplifier itself.

Note: This adapter cannot be used when additional tube brackets are installed. These must be removed before using the measurement adapter and reattached after the measurement is complete.

Measurement procedure
Determine the resistance of the adapter, including the test leads. Connect the adapter to the meter, but do not connect it between the tubes and the amplifier. Select the ohms range on the meter and note the reading, e.g. 1.1 ohms.
For the final measurement, insert the adapter between the tube and the de-energized amplifier, connect it to the meter, select the mV range and switch on the amplifier. When the amplifier has reached a stable operating condition, read the value in mV from the meter and calculate the quiescent current using Ohm's law.

Example
Measured voltage = 47 mV, adapter resistance = 1.1 ohms.
Formula (I = V / R) or in this case
Bias Current (in A) = Measured Value (Voltage in V) / Measured Value (Resistance in Ohm)
0.047V / 1.1 Ohm = 0.042A or 42mA

For the calculation of the correct bias current as well as further information on bias measurement please refer to further documents or the bias setting instructions in the info section as well as the manual of the amplifier itself.
This adapter is suitable for all EL34, 6L6, 6550, KT88, 6V6, 6CA7 and other tubes with the same pinout.

Attention HIGH VOLTAGE ! Measurements and work on tube amplifiers should only be done by qualified personnel.
