The meter can also be connected in series in an already existing
installation.
(See Fig.8)
Connect the multimeter to the 4-20mA terminals
of the DPH-64. Select the DC current range 20 or 200mA of the meter.
Go to the “CALIBRATE 4mA” window first. The DPH-64 now outputs the
count for 4.00mA. Dial up the measured current of the meter and press
VALUE. The current to the meter is corrected to read exactly 4.00mA
Use the same procedure for 20mA. If for some reasaon you do not get
the exact current the first time simply repeat the calibration.
F
If a configuration or number is accidentally changed in a setup window
exit by pressing MODE repeatedly to return to the main window. This
ensures no unwanted changes are saved. However make sure the mode
exited is enabled again..
