Hioki RM3545-02 - Setting the Measurement Speed

3.3 Setting the Measurement Speed
50
The measurement speed can be set to FAST, MED (medium), SLOW1, or SLOW2. The
MED (medium), SLOW1, and SLOW2 settings offer increased measurement precision
compared to the FAST setting as well as greater resistance to the effects of the external
environment.
If the setup is excessively susceptible to the effects of the external environment, shield the
measurement target and measurement leads adequately and twist the cables together.
See: "Appendix 8 Mitigating Noise" (p. A19)
A self-calibration that lasts about 5 ms is performed between measurements. To shorten
the measurement interval, set the self-calibration to “manual.”
See: "4.12 Maintaining Measurement Precision (Self-Calibration)" (p.92)

Press this to change the measurement speed.
When OVC is on, integration is performed twice. When LP is on, OVC is fixed to on.
When using the SLOW2 measurement speed with low-power resistance measurement on, the in-
strument will performing averaging with two iterations internally even if the averaging function is
set to off.
* When using the MUX mesurement terminals, the integration time is 1.0 ms only in the 10 m range.
