By now the parameter settings are completed. Pressing “F” and “V/A” simultaneously will
exit system parameter settings mode and return to the metering data mode.
3.4 I/O Parameter Settings
For meters with I/O module, under system parameter settings mode, hold “F” key for 3 sec-
onds to enter I/O settings mode. In I/O settings mode, key functions are the same as the
one in system parameter settings mode. “F” key is used to increase value by 1 for the flash-
ing digit. “V/A” key is used to confirm the flashing digit and move the cursor. At the last
digit of the parameter, pressing “V/A” key will confirm and go to the next screen. On any
screen, pressing “F” and “V/A” simultaneously will exit I/O parameter settings mode and
return to the system parameter settings mode.
I/O module has two types: AO type and RO type.
For AO type module, it offers two channel AO, which can be selected as voltage or cur-
rent type. AO parameter can be voltage, current and power. AO upper and lower limits
include "sign" and "percentage" digit. The sign digit has three options: repr),
represents(-), represents(±). The percentage digit's range is "0.00-1.00", representing "0%-
100%".
When AO parameter is set as voltage, the upper and lower limit setting is "0%-100%". When
AO parameter is set as current or power, there are four modes:“0% - +100%”;“0% - -100%”;“-
100 - +100%”and“0% - ±100%.
Note:
1. there is no "sign" digit when AO is set as voltage. "sign" digit is invisible when per-
centage is 0.
2. For limit setting,1.00 is 100%,0.00 is 0%,0.25 is 25%.
