Connecting the instrument to a computer
via RS-232C or USB
• Use a PC to control RM3545 and RM3544
-01
functions as well as
acquire measurement results.
(This capability does not include turning the instrument on and off or
configuring certain interface settings.)
• Connect the instrument to a commercially available RS-232C printer to
print measured values, including judgment results.
• Measured values can be automatically output. By using the instrument’s
USB keyboard mode, measured values can be entered into applications
such as spreadsheets and text editors without the need to install a spe-
cial USB driver in the computer.
• The sample PC application provides functionality for capturing data
based on trigger signals, performing interval measurement, conducting
communication tests, and loading captured data into Microsoft® Excel
or outputting it as a CSV file. The application can be downloaded from
Hioki’s website (http://www.hioki.com).

*1 Cannot be used in combination with a withstand voltage tester. When used with a withstand
voltage tester, the Z3003’s internal relay will cause an insulation breakdown, resulting in electric
shock or equipment damage.
*2 Assuming 24-hour operation, the guideline of 50 million cycles corresponds to approximately
1.5 years on a line operating at 1 sec. per workpiece or approximately 15 years on a line operating
at 10 sec. per workpiece.
•
About scanning time
The Z3003 switching time is 30 ms/ch.
The total scanning time can be calculated as follows:
(Switching time + measurement time including delay) × number of channels
For measurement time typical values, please see page 11.
