It’s like bringing a cartload of test equipment from the shop to the control room or the field. The TechChek 830-KP 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 precision 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-KP to both the input and output of the transmitter. The TechChek 830KP will simultaneously indicate the input and output of the transmitter 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 connection 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, 1 BAR, mBar, Atm, Kgf plus torr, inches and mm of mercury or water at a variety of temperatures. Characterized modules for laboratory accuracy in the shop, control room or field. Voltage Calibration Calibrate all your DC millivolt and voltage instrumentation. Source from 0.00 to 110.00 mV and 0.00 to 10.25 V. Read up to 110.00 mV, 11.00 V and 200.0 VDC. Temperature Calibration Source and Read directly in °C and °F for T/C types J, K, T, E, R, S & N and four Pt 100 Ohm, Ni 120 Ohm and Cu 10 Ohm RTDs. Resolution to 0.1°. Cold junction compensation tracks ambient temperature changes. Frequency Calibration Generate zero crossing square waves from 1 to 1000 Hz, 0.01 to 10.00 kHz and from 1 to 1000 CPM (Counts-Per- Minute). Built-in frequency counter measures Hz, kHz & CPM. Measure AC Voltage Check line voltage or mains from 0.0 to 250.0 volts AC. Great for troubleshooting power problems. Check Continuity Locate pairs of wires, open connections and shorts with Rear Label - Condensed Operation Guide 2 GENERAL TURN-ON Each time you turn on the TechChek 830-KP it runs through a self check then returns to the most recently selected settings. SOURCE - The three QUIK-CHEK outputs will be the same as previously stored. Each time a different function is selected, the associated three QUIK-CHEK outputs will be recalled. READ - The 830-KP is ready to measure the same signal as the last time it was used and automatically updates the MAX & MIN readings for recall at any time. CONNECTIONS TechChek 830-KP has protected banana jacks compatible with standard and safety banana plugs. Included with your TechChek are: a pair of safety test leads with test probes, safety alligator clips, standard alligator clips and spade lugs for attachment to a wide variety of instruments. An additional test lead and spade lug are also included for 3-Wire RTD connections. A second pair of test leads with right angled safety banana plugs and alligator clips for mA Read and Power Transmitter functions. Thermocouple connections are made through a miniature thermocouple socket. Optional KIT-1 includes T/C wires for Type J, T, E & K with miniature T/C plugs (not included). ! ! !! CAUTION! To prevent accidently overloading the instrument being tested, correctly set up the outputs before connecting the TechChek 830-KP to any instruments to be calibrated. 3 OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS OPERATING INSTRUCTIONS GENERAL GENERAL FIELD & BENCH USE TechChek 830-KP comes with a carrying case and a built-in tilt stand/hanger. The 830-KP is held securely in the case by VELCRO® for use with the carrying case open. The carrying case also has a snap- on belt loop which can be looped around a pipe or rail. The tilt stand is easily raised by pulling the stand until it locks into place. The stand can also be reversed for use as a hanger to suspend the 830-KP. CHANGING BATTERIES Low battery is indicated by a battery symbol on the display. Approximately four hours of operation remain before the LCD blanks and TechChek 830-KP shuts itself down. Turn the 830-KP off, loosen the captive screw securing the battery compartment and lift off the cover from the bottom of the case. The six “AA” batteries are easily removed and replaced (alkaline supplied and recommended). Replace the battery compartment cover by inserting the tabs and tightening the screw. 4 CONFIGURING TEMPERATURE SCALES The thermocouple and RTD ranges may be configured for full time use of °C, full time use of °F or selectable °C and °F operation. This configuration is part of the DEFA...
