1. Unpacking and Preparation
This chapter describes how to set up and start the AT8612.
Incoming Inspection
Power Requirements
Setting up the Fuse
Environmental Requirements
Cleaning
How to Remove the Handle
1.1 Incoming Inspection
After you have receive the instrument, carry out inspection during unpacking according
to the following procedures.
WARNING
If the outside of the instrument (such as the cover, front/rear panel, LCD screen, power
switch, and port connectors) appears to be damaged during transport, do not turn on the
power switch, in case you get an electrical shock.
Check whether the packing box or shock-absorbing material used to package the
instrument has been damaged.
Referring to <Packing List>in the packing box, check whether all packaged items
supplied together with the meter have been provided as per the specified optioned.
1.2 Power requirement
~Line: 110V/220VAC
Frequency: 47-440Hz
Power: <20VA
1.3 Setting up Fuse
Please use the following fuse type.
UL/CSAtype, Slow-Blow, 5×20-mm miniature fuse, 0.5A, 250 V
To verify and replace the fuse, remove the power cable and pull out the fuse holder.
Two fuses in Fuse Holder.
