DISPLAY CHARACTERISTICS
h
DISPLAY:
Nine Digit 0.56" LED with M (Mega) or K (Kilo) Hz; nano, micro,
or milli (n/u/m) Sec.; GT (GATE TIME); H (HOLD); and OF
(OVERFLOW) indicators. FUNCTION and GATE TIME are
user selected. OF display is shown when the count exceeds 999
999 999.
h
HOLD:
In the FREQUENCY, PERIOD, TOTAL, RPM modes,
measurement in progress is stopped; and the last complete
measurement is displayed. When HOLD is released, a new
measurement begins.
