1 Y our New T echChek 830-KP Lighten your load … take the T echChek 830-KP to every site. It ’ s like bringing a cartload of test equipment from the shop to the control room or the fi eld.
3 GENERAL TURN-ON Each time you turn on the T echChek 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.
5 GENERAL CONFIGURING TEMPERA TURE SCALES The thermocouple and RTD ranges may be con fi gured for full time use of ° C, full time use of ° F or selectable ° C and ° F operation. This con fi guration is part of the DEF AUL T SETTINGS below . AUTO-OFF T echChek 830-KP can be set up to turn itself off after 30 minutes of inactivity .
GENERAL SELECTING FUNCTIONS Press a function key to choose among mA, V , T/C, Ω , R TD, FREQ and PRESSURE. SELECTING RANGES Press the RANGE/TYPE pushbutton to select the desired range and scale.
9 CALIBRA TE MILLIAMP INPUTS mA, mA % (Percent of 4 to 20 mA), DP% (DP Flow) Choose this function to provide an output from 0.00 to 24.00 milliamps. The compliance voltage is a nominal 24 VDC to provide the driving power to your milliamp receivers. 1) Disconnect one or both input wires from the device to be calibrated.
11 CALIBRA TE VOL T AGE INPUTS V, m V Choose this function to provide an output from 0.00 mV to 1 10.00 mV and from 0.00 to 10.25 VDC. Current compliance up to 20 mA to provide the driving power to your voltage receivers.

19 READ FUNCTIONS Select read by pressing the DISPLA Y/SOURCE/READ pushbutton until the word READ appears on the LCD display . The READ functions measure the desired signal. Multiple scales are available for some functions. MIN/MAX T o read the Maximum or Minimum INPUT since READ mode was entered, simply press the MAX or MIN push-button.
21 READ DC and AC VOL T AGE OUTPUTS mV , V , Vhi and V ac Choose this function to measure from 0.00 to 1 10.00 millivolts (mV), 0.00 to 10.25 DC V olts (V). Use the high voltage connection to read from 0.0 to 200.0 VDC (Vhi). See the next page for V olts AC.
23 22 MEASURE THERMOCOUPLE SENSORS Choose this function to read a thermocouple. The input of the T echChek 830-KP is automatically cold junction compensated. 1) Disconnect the thermocouple from any instrument. 2) Press the T/C/RTD/ Ω pushbutton until the word TYPE & any T/C appear on the display .
25 CHECK CONTINUITY Choose this function to check continuity . A tone will sound and a sound symbol will appear on the display when the resistance between the leads is less than 100 Ohms. 1) Plug the leads into the T echChek 830-KP as shown below . 2) Press the T/C/RTD/ Ω pushbutton until the Ω symbol appears on the display .
27 BLA CK BLA CK RED 3 2 1 R TD Element OPERA TING INSTRUCTIONS MEASURE RTD SENSORS 26 MEASURE RTD SENSORS Choose this function to read an RTD. Three wires must be use for both 2 and three wire RTDs. 1) Disconnect the RTD from the instrument being calibrated.
