RANGE
A Auto: Automatic selection of measurement range
H Hold: Measurement range is held for manual selection
100 Measurement range (100m to 1M)
Table 3–2 Measurement range list
Recommended range: Recommended operating range for high accuracy measurement.
If out of the recommended range extremely, the measured value or data output may be
overflow.
Measureable range: Approximate range in which the measurement is possible.
The measurement may be possible even outside the range given above depending on the
measurement conditions, or the measurement may not be possible even within the
range given above due to incoming noise.
*1 When frequency > 20kHz, the recommended range, measureable range, and
meaurement accuracy are same as 100k range (Zr = 100k) even if 1M range is
specified.

current
The values in ( ) are when the minimum output impedance is 5, and the conditions for 5
are fulfilled. Allowable current peak value (instantaneous value) including DC bias current
is about 1.4 times the current value given in table (root-mean-square value).
