Page 13-5 Added to the “13.4 Error Codes”
The following error codes have been added to the list.
Error Codes Error Corrective Action
013 Attempted “REP RECALL START” without hourly,
daily, or monthly report data.
032 Set to contiguous channels on the power monitor
module.
Enter a correct channel.
047 Entered a wiring method for which there is no
setting for the power monitor module.
Enter the correct wiring method.
107 Attempted to change ranges or time while report
was starting.
Do not make changes.
131 Media write error Exchange the medium.
137 Attempted to start computation or execute a
procedure during saving of settings to a medium
or while reading from a medium.
Start the procedure or computation after completion of
the media operation.
138 Media drive error Exchange the medium. If the error occurs again after
exchanging the medium, servicing is required.
170 The IP address does not belong to any of the
classes, A, B, or C.
Set the correct IP address.
171 There is a hole in the mask or the host address
section is not released.
Set the correct subnet mask.
172 The net address section including the subnet does
not match the subnet section of the IP address.
Set the correct net address.
173 The host address section of the IP address is
either all zeroes or all ones.
Set the correct IP address.

Scaling
Measurement accuracy for scaling: measurement accuracy for scaling (digits) = measurement
accuracy (digits) × scaling span (digits) / measurement span (digits) + 2 digits. Numbers below
the decimal point are rounded up.
±(((0.05/100) Ч 5000) + 2) Ч (2000/4000) + 2 = ±4.25
Measurement accuracy = ±5 digits = ±0.005 V

*1
Pollution degree based on IEC61010-1, DSA22.2 No 61010-1.
2
*2
Warm-up time
At least 30 minutes after power switch-on.
*1 Describes a number which defines a transient overvoltage condition. It implies the regulation for impulse
withstand voltage. “II” applies to electrical equipment which is supplied from fixed installations like distribution
boards.
*2 Describes the degree to which a solid, liquid, or gas which deteriorates dielectric strength or surface
resistivity is adhering. “2” applies to normal indoor atmosphere. Normally, only non-conductive pollution
occurs.
