other parameters such as temperature
and high currents. Kits containing a
useful selection of such transducers
for both the HVAC and the service in-
dustry are available

Test Result Storage
(BM2500 Series)
Up to 99 distribution board references
each with up to 99 circuit references
may be specified. Test results may be
stored against any circuit and distribu-
tion board combination.
Data may be recalled to the display,
printed, or downloaded to a printer or
pc.
Communications (BM2500 Series)
RS232 9 pin male D connector
Baud rate 9600
Printer Output (BM2500 Series)

(BMM2500 Series)
Language may be changed using AVO
Download Manager Software supplied.
Data Logging (BM2500 Series)
The instruments may be set to continu-
ously record any one of the measurable
parameters e.g. voltage, insulation re-
sistance etc. The logging interval may
also be adjusted to suit the application.
Logging Interval
10 s to 1990 s in 10 s increments
Number of samples
Approximately 300
Accuracy
