READ DC and AC VOLTAGE OUTPUTS
mV, V, Vhi and Vac
Choose this function to measure from 0.00 to 110.00 millivolts (mV),
0.00 to 10.25 DC Volts (V). Use the high voltage connection to read
from 0.0 to 200.0 VDC (Vhi). See the next page for Volts AC.
1) Press the MILLIAMP/V push-button until mV, V, Vhi or VAC
appear on the display
3) Press the DISPLAY/SOURCE/READ push-button until READ
appears on the display
4) Press the TYPE/ENG UNITS push-button to select mV, V, Vhi or
VAC on the display
5) Connect the red READ (+) lead and the black READ (-) lead of
the calibrator across the voltage to be measured.
Signals above or below those available for the currently selected
range will be indicated by OVER and UNDER on the display.

READ MILLIAMP OUTPUTS
mA, mA % (Percent of 4 to 20 mA), DP% (DP Flow)
Choose this function to measure from 0.00 to +24.00 milliamps.
1) Open the current loop at any convenient point along the signal
path
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 READ
appears on the display
4) Press the mA/%/% DP FLOW push-button to display mA, % 4-20
or % DP Flow.
5) Connect the red READ (+) lead of the calibrator to the more
positive point of the break and the black READ lead (-) to the
more negative
Display the present reading, Maximum or Minimum by pressing
the READ, MAX or MIN push-buttons. If the TechChek 830-KP is
connected in the wrong polarity, the word POL will flash on the
display. Simply reverse the leads for correct indication.
