Your New TechChek 830-KP
Lighten your load…take the TechChek 830-KP 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-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...

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.

CONFIGURING TEMPERATURE SCALESThe 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 DEFAULT SETTINGS below.
AUTO-OFFTechChek 830-KP can be set up to turn itself off after 30 minutes
of inactivity. The internal timer is reset to 30 minutes each time a
pushbutton is pressed.
DEFAULT SETTINGS
TechChek 830-KP may be restored to the factory default setting.
This will reset the HI and LO...

CALIBRATE 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.
2) Press the MILLIAMP/V push-button until mA or mA and %
appear on the display
3) Press the DISPLAY/SOURCE/READ push-button until SOURCE
or 2-WIRE appear on the display
4) If 2-WIRE is on...

CALIBRATE VOLTAGE INPUTS
V,  m V
Choose this function to provide an output from 0.00 mV to 110.00
mV and from 0.00 to 10.25 VDC. Current compliance up to 20 mA
to provide the driving power to your voltage receivers.
1) Disconnect one or both input wires from the device to be
calibrated
2) Press the MILLIAMP/V push-button until V or mV appear on
the display
3) Press the DISPLAY/SOURCE/READ push-button until SOURCE
and V or mV appear on the display
4) Press the TYPE/ENG UNITS push-button once to switch...

CHECK 1-5 VOLT INPUTSWITHOUT DISCONNECTING WIRESMost 1-5 Volt receivers in 4-20mA loops have a 250 Ohm
resistor across the input of the receiver. This resistor may be
mounted internally or externally. TechChek 830-KP is connected
directly across the input of the 1-5 Volt receiver...

CALIBRATE RESISTANCE INPUTSChoose this function to simulate a resistance into a variety of
instruments. 
1) Disconnect one or both input wires from the device to be
calibrated
2) Press the T/C/RTD/Ωpushbutton until the Ωsymbol appears
on the display.
3) Press the DISPLAY/SOURCE/READ push-button until SOURCE
appears on the display
4) Connect the red SOURCE lead of the calibrator to the plus (+)
input of the device and the black SOURCE lead to the minus (-). 
Output resistance is continuously adjustable...
