The number of logged records includes all records currently logged in the memory partition. The number of the
new records includes the number of records that are logged after the last read request has been issued for the
memory partition.

1. Except for the signed power factor (see Note 3 to Table 4-23), the output scale is linear within the value range. The scale
range will be inverted if the full scale specified is less than the zero scale.
2. For bi-directional analog output (±1 mA), the zero scale corresponds to the center of the scale range (0 mA) and the
direction of the current matches the sign of the output parameter. For signed (bi-directional) values, such as powers and
signed power factor, the scale is always symmetrical with regard to 0 mA, and the full scale corresponds to +1 mA output
for positive readings and to -1 mA output for negative readings. For these, the zero scale (0 mA output) is permanently set
in the instrument to zero for all parameters except the signed power factor for which it is set to 1.000. In the write
request, the zero scale is ignored. No error will occur when you attempt to change it. Unsigned parameters are output
within the current range 0 to +1 mA and can be scaled using both zero and full scales as in the case of single-ended
analog output.
