To set the limits, proceed as follows:
First set the desired measurement range manually by means of the
“RANGE” button. Press the “ENTER MENU” button. The menu appears in
the top line. The first symbol (for reference value measurement) flashes.
Using the “< >” button, move from symbol to symbol. Press this button
until the symbol “LMT” flashes. Confirm the selection with the “ENTER”
button. As a result of this, three sub-displays appear. In the left sub-
display the current measured value is indicated. The centre sub-display
shows the upper limit and the right sub-display shows the lower limit.
The right sub-display flashes. Now press the button “< >” by pressing the
right (+) or left (-) button edge until the desired lower limit is shown.
Confirm by pressing the “ENTER” button. The centre sub-display flashes.
Proceed with setting the upper limit as for the lower. Press the “ENTER”
button once in confirmation. Depending on the level of the measured
value, “PASS” is now displayed when the measured value lies between
the upper and lower limits. “LO” is displayed when the measured value is
lower than the set lower limit. “HI” is displayed when the measured
value is higher than the upper set limit.
5.16 “PH” peak hold measurement sub-function (not VC 630)
With the peak hold function, the highest-occurring measured value is
captured and indicated. Press the “ENTER MENU” button. The menu
appears in the top line. The first symbol (for reference value
measurement) flashes. Using the “< >” button, move from symbol to
symbol. Press this button until the symbol “PH” flashes. Confirm the
input with the “ENTER” button. The peak value captured within
milliseconds (ms) is displayed in the centre sub-display. The currently-
measured value can be read in the main display. To exit the “PH”
function, press the “ENTER MENU” button once briefly or press the
“AC/DC” button or one of the measurement function buttons around
the “ENTER MENU” button => the relevant screen appears.
5.17 “REC” record measured value and “RCLL” recall measured
value sub-functions
Up to 10 measured values can be stored and recalled by means of the
sub-functions “REC” (record) and “RCLL” (recall). The measured values

Clearly and above all simultaneously, the instantaneously-measured
value, the maximum value (centre sub-display) and the minimum value
(right sub-display) are now displayed on the whole screen area.
To exit the “MIN/MAX” function, press the “ENTER MENU” button once
briefly or the “AC/DC” button or one of the measurement function
buttons around the “ENTER MENU” button => the relevant screen
appears.
5.14 “TIME” (time-capture) sub-function
During measurement a clock can be started by means of the “TIME”
function, which records the time from the start of measurement. The
time stored is 24 hours maximum. Until one hour has elapsed, the time is
presented in minutes and seconds, thereafter in hours and minutes.
To set the clock, proceed as follows:
During or prior to measurement press the “ENTER MENU” button. The
menu appears in the top line. The first symbol (for reference value
measurement) flashes. Using the “< >” button, move from symbol to
symbol. Press this button until the “TIME” symbol flashes. Confirm the
selection with the “ENTER” button. The clock is displayed in the left sub-
display. The clock can be started and stopped and reset to zero using the
“< >” button. Pressing once on the left arrow (left button edge) stops or
starts the clock. Pressing once on the right arrow (right button edge)
resets the clock to zero. To exit the “TIME” function, press the “ENTER
MENU” button once briefly or press the “AC/DC” button or one of the
measurement function buttons around the “ENTER MENU” button =>
the relevant screen appears.
5.15 “LMT” comparison value measurement sub-function
(VC 670 only)
So-called comparison measurements are possible by means of the “LMT”
(limit) function. High/low comparisons can be made in this sub-function,
in which the instantaneously-measured value is compared with the
highest and lowest reference values stored. To exit the “LMT” function,
press the “ENTER MENU” button once briefly or press the “AC/DC”
button or one of the measurement function buttons around the “ENTER
MENU” button => the relevant screen appears.
