6.4 Entering Parameters – SETUP Menu
rAtE – set the sampling rate (METRAHIT EXTRA only)
The sampling rate specifies the time interval after which the
respective measured value is transmitted to the interface, or to
measured value memory.
Any one of the following rates can be selected:
00:00.1, 00:00.2, 00:00.5, 00:01.0, 00:02.0, 00:05.0
[h:mm:ss.t] (h = hours, m = minutes, s = sec.,
t = tenths of a sec.
)
0:00:10, 0:00:20, 0:00:30, 0:00:40, 0:00:50, 0:01:00, 0:02:00, 0:05:00,
0:10:00, 0:20:00, 0:30:00, 0:40:00, 0:50:00, 1:00:00, 2:00:00, 3:00:00,
4:00:00, 5:00:00, 6:00:00, 7:00:00, 8:00:00, 9:00:00

SET rAtE
00:00.1 ... 00:00.5 ... 9:00:00
(00:00.5 = 0.5 seconds = default value)
The last value is retained.
noFiL – quick display of measured values
For the following functions, a quicker display update rate of 5 dis-
play values per second (noFiL=ON) instead of 2 display values per
second (noFiL=OFF) can be set:
VDC, ADC with clamp, ADC di-
rect,
, diode measurement, continuity test.

(OFF =
Standard value*/default setting)
* All specifications refer to the default update rate with measuring para-
meter noFiL = OFF (default).
