Source and
read T/C’s over the entire industrial temperature range
with Altek’s Model 422 Thermocouple Calibrator. Use with
transmitters, recorders, controllers, alarms,
indicators, data acquisition and computer systems.
Switch between 14 T/C types or millivolts.
High accuracy and stability is achieved through Altek’s
exclusive isothermal block. Make your connections
directly with thermocouple wire or with miniature
thermocouple connectors.
Field customize the Model 422 to lock-in 0.1° or 1°
resolution, fixed °F or °C or front panel selectable
°F/°C operation. A shrouded miniature thermocouple
connector receptacle plus terminal crews allow for easy
hookups. Built in protection guards the Model 422
against mis-connection to 120 Volts AC or DC, in any
mode.
The Model 422 turns on to the T/C type last used. Other
T/C types may be selected each time the unit is turned
on. If you use less than 14 T/C types, you can create
your own T/C List. By following a simple setup procedure
you can deselect unwanted T/C types to customize T/C
types available at turn on.
Select resolution of 0.1° or 1° for the full listed
range of all thermocouple types. Millivolts allows 1
microvolt resolution from -99.999 to 99.999mV. The Model
422 simulates key temperatures for repetitive
calibrations. "Quik-Chek" function stores three output
temperatures for each T/C type (45 total) for real
convenience. Three memories are retained for each
thermocouple type even when the power is off.
Turn the knob to check trip points, controller action or
hysteresis. The fast response 422 sets quickly without
overshoot but allows slow changes at your own rate.
The Model 422 display gives you fast, accurate
temperature measurement with 0.1 and 1 degree or with
0.001 millivolt resolution. High resistance or open T/Cs
and leads are detected and indicated on the LCD display.
Two readings per second track fast moving temperatures.
"MAX" and "MIN" memories are continuously updated from
turn-on or whenever the "RESET" pushbutton is pressed.
The Model 422 gives you a handy tool to monitor
temperatures for drift or control deviation. Just flip
the "Quik-Chek" switch to display the minimum and
maximum temperature since reset.
Each time the Model 422 is turned on, the LCD will
display all segments for 1 second. It then displays the
currently selected thermocouple type or mV for
approximately 3 seconds. If °C/°F operation has been
selected the currently selected temperature scale of °C
or °F will display. |
