    Your New TechChek 830
    Lighten your load…take the TechChek 830 to every site.
    It’s like bringing a cartload of test equipment from the shop
    to the control room or the field. The TechChek 830 sources
    and reads DC like a milliamp or voltage calibrator, simulates
    and measures T/Cs & RTDs like a temperature calibrator,
    generates and counts frequency and Counts-Per-Minute
    like a frequency calibrator and displays pressure like a preci-
    sion test gauge. Troubleshooting? It checks continuity with a
    beeper and measures AC line voltage like a multimeter!Calibrate Milliamp Inputs
    Calibrate controllers, recorders and other devices in 4
    to 20 or 0 to 20 mA loops.  Source and read 0.00 to 24.00
    mA, or Simulate a 2-Wire Transmitter. Use the optional AC
    adaptor for continuous operation. Display to 0.01 mA , 0.1
    % of 4 to 20 and 0.1 % DP Flow.Calibrate 2-Wire Transmitters
    Easily calibrate 2-Wire Pressure and Electronic
    Transmitters by connecting the TechChek 830 to both the
    input and output of the transmitter. The TechChek 830 will
    simultaneously indicate the input and output of the transmit-
    ter on the graphical display.Calibrate Pressure Systems
    Read pressure with extreme accuracy using an external
    QuikCal pressure module in a companion ModPak module
    holder. Attach the module directly to the pressure connec-
    tion for the best accuracy or with optional tubing for tight
    spots. Display to five digits within 0.025% of reading in up
    to 20 engineering units including psi, pa, Kpa, Mpa, BAR,
    mBar, Atm, Kgf plus torr, inches and mm of mercury orGENERAL INFORMATION

    CHECK 1-5 VOLT INPUTS
    WITHOUT DISCONNECTING WIRES
    Most 1-5 Volt receivers in 4-20mA loops have a 250 Ohm resis-
    tor across the input of the receiver. This resistor may be mounted
    internally or externally. TechChek 830 is connected directly across
    the input of the 1-5 Volt receiver without disconnecting any field
    wiring. This saves a great deal of time when a large number of
    voltage receivers, such as chart recorders or computer systems,
    require calibration.
    Make certain that changing the signal input will not disturb the
    process or cause unexpected alarms when checking on-line
    instruments. It is important to remember the 830 drives only the
    device to which it is connected.It has no effect on other devices
    in the 4 to 20 mA loop. TechChek 830 will clamp the selected
    value in the mV and V Ranges to the maximum source or sink
    current of >16 mA.
    1) Turn the Selector Knob to V
    2) Press the DISPLAY/SOURCE/READ push-button until SOURCE
    and V or mV appear on the display
    3) Press the TYPE/ENG UNITS push-button once to switch

    Note on 4-Wire Connections:
    The TechChek 830 may be used to calibrate instruments
    requiring a 4-Wire RTD connection. This connection is valid
    only when the lead wires included with the 830 are used to
    connect the 830 directly to the instrument. Use of longer wires
    can cause errors in the output setting.
    For long 4-Wire cable runs use the 3-Wire connection and add
    a stacking banana jack (not available from Altek) to connect a
    second wire to jack #1. Connect this extra wire to the fourth
    wire field connection.
