SOURCE MODE
Select source by pressing the DISPLAY/SOURCE/READ
pushbutton until the word SOURCE appears on the LCD display.
To change the output value, press the UP or DOWN key for each
digit. To ramp the output press and hold any UP or DOWN
pushbutton. The display will continue to change in increments
corresponding to the digit being changed and will automatically
carry up and down until the limits of the range are reached. This
function operates in all three output positions (HI, SET & LO).
STORING QUIK-CHEK OUTPUTS
1) Press HI or LO
2) Press the UP/DOWN keys to desired
value
3) Press the STORE push-button
The LCD will flash once to show that the
value was saved
If a value is in the SET position and you want
that value stored in HI or LO, press and hold
the STORE push-button, then press the HI
or LO push-button. The display will flash
once to indicate the value has been stored.
Then release both push-buttons.
RECALLING QUIK-CHEK OUTPUTS
When you need a stored value just press a
Quik-Chek push-button. Any value for the
selected range may be stored in HI & LO.
The TechChek 830-KP remembers the HI,
LO and SET values for each function with the
power on or off. Each time a different function
is selected, the last three QUIK-CHEK values
for that function will be recalled.
