displayed, press the button once to
store the reading as the “standard” value or
test reference value. At this point, the “
TOL ”
will be displayed on the screen, indicating that
the tolerance mode is activated.
3. To select the tolerance range, press the
button once more. For each button
press, the meter will cycle through the
tolerance range percentage in this order:
1% ,
5% , 10% , 20% . These percentage ranges will
also be indicated on the LCD display by the
indicators “
1% ”, “ 5% ”, “ 10% ”, or “ 20% ”
respectively. The component to be tested will
be verified within the selected tolerance % of
the “standard” value or test reference value
(as configured from step 2).
4. Within a few seconds, an audible tone will be
heard.
One single “beep” or tone means the
component is within tolerance.
Three “beeps” or tones means the component
is out of tolerance.
