Setting the Measurement Speed
3.3 Setting the Measurement Speed
The slower the measurement speed, the higher the measurement accuracy. In addition to setting
the measurement speed to
FAST
,
MEDIUM
, or
SLOW
, you can set the integration time as desired.
For more information: “Setting the integration time” (p. 67)
The
FAST
,
MEDIUM
, and
SLOW
settings differ in terms of integration time as follows:

* PLC stands for power line cycle. The interval of 1 PLC is equivalent to one cycle of the supplied
power source. If using the instrument in an area with 50 Hz power, 1 PLC = 1/50 = 20 ms. If using
the instrument in an area with 60 Hz power, 1 PLC = 1/60 = 16.7 ms.

key.
The measurement speed will change each time
the key is pressed (indicated by the box below).
You can set the desired integration time using
the touch panel.

•If measurement is prone to the influence of the external environment: See “Appx. 4 Noise
Countermeasures” (p. Appx.8) for more information.
•The instrument performs self-calibration between measurements. For more information about
measurement times, see “11.6 Timing Chart” (p. 139).
