Disabling Auto-Power-Off (APO)
Press-and-hold the HOLD button while sliding the function-selector to a (designated)
function-selector position. This disables the Auto-Power-Off feature of the functions on
that particular function-selector position. The LCD displays “
” & “ ” to confirm
activation right after the HOLD button is released. Slide the function-selector to any other
positions then resumes Auto-Power-Off feature.
RS232C PC computer interface capabilities
The instrument equips with an optical isolated data output port at the bottom case near
the battery compartment. Optional purchase PC interface kit RS232 KIT2 (including
Optical Adapter Back, RS232 Cable & Bs15x Software CD) is required to connect the
meter to PC computer thru RS232C protocol. The RS232C Data Recording System
software Bs15x includes a digital meter, an analog meter, a comparator meter, and a
Data Graphical recorder. Refer to the README file comes with the interface kit for
further details.
Press-and-hold the Hz button while sliding the function-selector to a (designated)
function-selector position. This enables data output of the functions on that particular
function-selector position. The LCD displays “
” to confirm activation right after the Hz
button is released. Slide the function-selector to any other positions then disables data
output.
5) MAINTENANCE
WARNING
To avoid electrical shock, disconnect the meter from any circuit, remove the test leads
from the input jacks and turn OFF the meter before opening the case. Do not operate
with open case.
Trouble Shooting
If the instrument fails to operate, check batteries and test leads etc., and replace as
necessary. Double check operating procedure as described in this user’s manual
If the instrument voltage-resistance input terminal has subjected to high voltage transient
(caused by lightning or switching surge to the system) by accident or abnormal
conditions of operation, the series fusible resistors will be blown off (become high
impedance) like fuses to protect the user and the instrument. Most measuring functions
through this terminal will then be open circuit. The series fusible resistors and the spark
gaps should then be replaced by qualified technician. Refer to the LIMITED WARRANTY
section for obtaining warranty or repairing service.
