2.3.3 Operating the Computer
Megohmmeter allows wireless data exchange with an external device (PC). To ensure
data transmission to PC, a Bluetooth device is required. When it is not built-in, an external
Bluetooth-USB adapter is required.
Reception and transmission are performed by operating system tools of the PC. Data
are transmitted and saved in PC as text files containing the information stored in the instrument
memory. To make data handling easier, a specialized program
“
RS-terminal
”
is used; it allows
assigning the proper names to objects and cells (name lengths is up to ten digits), generating
the reports, etc. The program and its detailed description can be downloaded from the
company's site www.radio-service.ru.
For data exchange with a computer it is required:
- turn on PC and run RS-terminal program;
- on the instrument, which shall be switched on, enter the mode
“
Память
”
(Memory),
select option
“
CONNECTION TO PC
”
;
- in the RS-terminal window, select all the necessary objects and cells. A file with
measurement results can be copied and edited by any text editor.
Note. Computer shall be located within the sight at a distance of not more than 8 meters
from the megohmmeter.
2.3.4 Voltage measurement
After the instrument is switched on and the mode of insulation resistance measurement
is selected by button
, the instrument sets to the voltmeter mode, it measures and shows
on display the actual voltage value between sockets "+" and "-" and its type (DC or AC voltage).
Example of indication is shown in Figure 2.7.
Note. Actual voltage value between sockets "+" and "-" shall be maximum 770 V,
between other sockets
–
maximum 300 V. Failure to comply with this rule can cause the
instrument breakdown.
