Extended Resolution Manual
Operation
When operated in the Manual Range mode, the
TC818A extends resolution by 50% for current, volt-
age,
and
resistance
measurements.
Resolution
increases to 3000 counts from 2000 counts. The
extended resolution feature operates only in the
2000k
Ω and 2000V ranges during auto-range
operation.
In the Extended Resolution Operating mode, readings
above 1999 are displayed with a blinking “1” most sig-
nificant digit. The blinking “1” should be interpreted as
the digit 2. The three least significant digits display data
normally. The bar graph LCD will be fully extended.
An input over range condition causes the most signifi-
cant digit (MSD) to blink and sets the three least signif-
icant digits (LSDs) to display “000.” The buzzer output
is enabled for input voltage and current signals with
readings greater than 2000 counts in both manual and
auto-range operations.
For resistance measurements, the buzzer signal does
not indicate an over range condition. The buzzer is
used to indicate continuity. Continuity is defined as a
resistance reading less than 19 counts.
