Hioki expresses accuracy as error limit values specified in terms of percentages relative to reading and full
scale, and digits.
Resistance Measurement
*1: BT3562A, BT3562, BT3563A, and BT3563 only
*2: Measurement current error within ±10%
*3: Add ± 3 digits for EX.FAST, or ± 2 digits for FAST and MEDIUM sampling rates.
Add ± 30 digits for EX.FAST, or ± 10 digits for FAST, or ± 5 digits for MEDIUM sampling rates (3 m

range).
Voltage Measurement
*4: BT3562A only
*5: BT3563A and BT3563 only
*6: Add ± 3 digits for EX.FAST, or ± 2 digits for FAST and MEDIUM sampling rates.
Warm-up time At least 30 minutes
Self calibration Except when using SLOW sampling, self-calibration should be executed
after warm-up.
Ambient temperature after self-calibration should be maintained within ± 2
°
C.
Measurement state Measurement taken in the same set-up as was in place when zero adjust -
ment was performed, including identical probe profile and placement.
Probe profile must not be changed during measurement.
Full scale (Maximum displayable value)
Refers to the maximum displayable value of each measurement range.
The instrument has measurement ranges whose values are equal to the maximum displayable values.
The limit values of full-scale errors are expressed in percent of full scale (% of full scale, % f.s.).
Reading (Displayed value)
Refers to the displayed value of the measuring instrument.
The limit values of reading errors are expressed in percent of reading (% of reading, % rdg.).
Digits
(Resolution)
Refers to the smallest change in the indication on the digital measuring instrument, i.e., the numeral one in the
rightmost place. The limit values of digit errors are expressed in terms of digits (dgt.).
