    Model 22
    • Direct temperature output22 precise steps
    • 0.1% accuracy25, 50, or 100 degree resolution
    • Rugged designField, shop and control room use
    • Pocket sized1 year battery life
    • Models for types B, E, J, K, R, S, T°C & °F cold-junction compensatedAltek Model 22 Thermocouple Sources provide 22
    precise temperatures for inputs to transmitters,
    recorders, controllers, alarms, data acquisition and
    computer systems. The Model 22 provides
    thermocouple wire output and is cold-junction
    compensated for ambient temperature variations.
    Conformity to the particular thermocouple vs millivolt
    curve is in accordance with the latest ASTM and IPTS
    standards for exact temperature simulation. 
    Thermocouple types B, E, J, K, R, S and T are
    available in both degrees F and C. Resolution is 25,
    50 or 100 degrees, corresponding to full scale output
    of 500, 1000, 1700, 2100 and 3100 degrees
    respectively.
    Dual ranges, with an individual “ON” position for each
    range, allow quick, easy settings for any output.
    Calibrated accuracy is ±0.1% of span ±1 degree.
    Negative temperatures add ±2 degrees.
    Two built-in AA cells provide power for one year of
    everyday use. A front panel LED pulses every time the
    Model 22 is turned on to indicate proper battery
    voltage.
    The low cost Altek Model 22 is a complete, compact
    source for checkout and calibration of all
    thermocouple instruments in the field, shop or control
    room.
    General description
    Select the Altek Model 22 for the correct thermocouple type, the
    desired temperature scale (F or C), and range. Connect the Model
    22 to the input terminals of the instrument to be tested, the field
    mounted head or junction box terminals.
    Cold-junction compensation and instantaneous automatic
    standardization is built into the Model 22.
    Set the temperature selection switch to the desired temperature
    and slide the “ON” switch to the selected scale. The Battery Check
    LED will pulse once indicating proper battery voltage. If no pulse is
    seen, the batteries should be replaced with 2 “AA” cells. Alkaline
    cells are preferred for longest life and widest operating temperature
    range.
    End point calibration temperatures of the instrument are then
    selected on the Model 22 and any required adjustments are made.
    Intermediate points may then be selected to verify instrument
    linearity or check critical points.
