    Test lamps L1-3 (L13, L1 3, L 1-3, L-1-3, L 1 3)
    Test lamps L1-3 - an instrument designed to measure the basic electrical parameters of radio tubes, as well as removing the static characteristics.

    Measurement range:
    - Filament voltage - 3V 7.5 V 15V;
    - The voltage on the grid 1 - 1.5 V 3V 7.5 V, 15 V;
    - The voltage on the grid 2 - 75V, 150V, 300V;
    - Anode voltage - 15V, 75V, 150V, 300S;
    - Current at the anode and the emission diodes - 1.5 mA, 3 mA, 7.5 mA, 15 mA, 30 mA, 75mA, 150mA;
    - Current net 2 - 0.75 mA, 1.5 mA, 3 mA, 7.5 mA, 15 mA;
    - Backlash 1 and the anode current at the beginning of characteristics - 0.75 mA: 3mkA; 15mkA; 30MKA; 150mkA;
    - Rectified Current - 150mA, 300mA;
    - Slope - 0.75 mA / V, 1.5 mA / V, 3 mA / V, 7.5 mA / V, 15 mA / V, 30 mA / V, 75mA / V.

    Power - AC 220V or 127V, 50Hz, 115V, 400Hz.
    Power Consumption - 300W, 450W (at test lamp 5TSZS).
    Dimensions - 515×317×228mm.
    Weight - up to 22kg.

    Testers lamps L1-3 allow measurement receiver-amplifier and a low-power generator (with a power dissipation of the anode to 25W) lamps, rectifier tubes, diodes, voltage regulators, and discharge in accordance with the specifications or in the conventional mode.

    Specifications L1-3

    In addition, the test of L1-3 allows you to measure in heated-lights:
    - The leakage current between the cathode and heater at voltages of 100V and 250V (plus on the cathode minus the heater on);
    - The leakage current between the electrodes at voltages of 100V and 250V.

    Test L1-3 supplies the electrodes bulbs the following voltages:
    - On the heat - from 1V to 14V at currents up to 1.2 A;
    - A grid 1 - 0 to-65V and-100V fixed voltage;
    - 2 on the grid - from 10V to 300V with a current up to 15mA;
    - The anode - from 5V to 300V with a current up to 100 mA;
    - AC voltage rectifier tubes for the test - 2 × 350V, 400V × 2, 2 × 450 V, 2 × 500V.

    The testers L1-3 in their work may allow the following error:
    - To measure the filament voltage, anode grid 1, the grid 2, the anode current, the grid 2, and the rectified current test rectifier tubes - ± 1,5% of the span of each of the scales;
    - For measuring the inverse current and the grid 1 in the beginning of the current characteristics - ± 2,5% of the span of each of the scales;
    - To measure the slope - ± 2,5% of full-scale each of the scales.

    Devices L1-3 under the influence of various factors can alter his testimony:
    - When the ambient temperature within the operating temperature range - less than 1.2% for every 10 ᵒ C change in temperature of the upper limit of measurement of each of the scales;
    - Change reading lamp instrumentation caused by changes in ambient temperature within the operating temperature range - less than 2% for every 10 ᵒ C change in temperature of the upper limit of measurement of each of the scales.

    The testers L1-3 are designed for use under the following conditions:
    - Air temperature +20 ° C;
    - Relative humidity - 95%;
    - Atmospheric pressure of 750 mm Hg
    The manufacturer guarantees, testers lamps L1-3 correspond to the technical requirements under normal use, storage, transportation and installation.
    Test tubes L1-3 complies with the requirements ensuring the safety of life, health, consumer and environmental protection.
