Full high performance digital tube tester kit, wired, adjusted & ready to use.

 

Manual available here:

 

https://www.radioelec.com/images/Image/Documentation/DuoKit_2_user_guide.pdf


This kit is an evolution of the complete digital kit offered since 3 years. With this new module testing of diodes and valves up to a plate current of 340mA is now possible.


This kit consists of a main card shown in photo 1 and a set
of pre-wired peripheral elements + power sources, shown in photo 2.


Photo 4 is a view of the ready-to-use assembly.


Important: The heater power supply is not included in this kit because many users already have a suitable transformer. A regulated triple voltage power supply module (4v - 5v - 6.3V / 4A) is available on request.


The characteristics and performance are vastly superior to the whole traditional lampmeters and can measure a very wide range of tubes including valves, diodes and magic eye.


The display is shown in photo 3. It indicates the test parameters and the result in real time:


A: Plate voltage, adjustable from 2 to 450V +/- 5%


G2: Grid voltage 2 (screen), adjustable from 10 to 350V +/- 5%


G1: Grid voltage 1 (polarization), adjustable from 0 to -100V +/- 5% by 10-turn potentiometer


The plate current is displayed in 2 ranges in the lower right corner:


0 to 34mA, display on 2 digits + one decimal: XX, XmA


> 34mA, display on 3 digits: XXXmA


The maximum measurable current is 340mA for all types of tubes.


Complete documentation on request by giving me a valid e-mail address.


Summary of features:
 
Dimensions:


Module: 130 mm x 110 mm maximum height 30mm


Backlit LCD display: 25 x 70 mm.


Single power supply: 110/230 V or on 12V battery via a converter
offered as an option.


Power from mains: 25W (35W max.) On mains and approximately 2A on 12V battery


Plate voltage: adjustable from 2 to 450 V


Screen voltage: adjustable from 10 V to 350 V


Grid 1 voltage: 0 to - 100 V (by 10-turn potentiometer)


Plate current range: 0 to 340 mA in 2 automatic sub-ranges: 0 to 34.0 mA (resolution 0.1mA) then 34 to 340 mA (resolution 1mA)


Neon short-circuit indicator in the plate.


Short-circuit protection: total


Overall accuracy: +/- 5% +/- 1 digit


Note: These values ​​are real, the use of a microprocessor allows a ultra fast measurement mode which minimizes power feed .

 

Few traditional lamp meters are capable of such measurements because they require heavy and bulky power supplies - the famous Metrix 310, for example, is limited to 100 mA of plate current.


The operation of the device is very simple: test parameters are adjusted, by means of 3 potentiometers, anode voltage, screen voltage (for tetrodes, penthodes, etc ...) and the bias voltage gate at the desired values ​​and, simultaneously, the plate currentcorresponding is displayed on the lcd screen.


The measurements are carried out at a rate of 2 per second which allows continuous reading parameters and result.
