9. 2.6 VB±<n>
This command is to adjust the UPS sampled baery voltage value (the baery voltage displayed on LCD) to
match the baery voltage you measure with a mulmeter. The format is:
Computer: VB±<n><Enter> UPS: (ACK or (NAK*
*: If UPS accepts this command, responds ACK. Otherwise, responds NAK Voltage adjustment step: <XX>, XX is
two digits: 00, 01,...,99
For example:
Computer: VB-01<Enter> UPS: (ACK
Meanings: Baery sampling voltage will decrease about 0.1Volt.
9.2.7 QVFW
QVFM means to request the version of the rmware. The command format is: Computer: QVFM<Enter>
UPS: (VERFW: <NNNNN.NN>
<N> is a HEX number from 0...9 or A…F.
Example:
Computer: QVFW<Enter> UPS: (VERFW: <00123.01>
Meanings: 00123 is the rmware series number and 01 is the version.
9.2.8 OC±<n>
This command is to regulate the UPS sampled output current value (which you can ready by QGS command) to
match your measured value. The format is:
Computer: OC+<XX>< Enter >
UPS: (ACK<cr> if UPS accepts this command, otherwise, responds (NAK<cr> Computer: OC-<XX>< Enter >
UPS: (ACK<cr> if UPS accepts this command, otherwise, responds (NAK<cr>
<XX> is two digits which ranging from 00, 01…… to99. 99 means 9.9A For example:
Computer: OC-01<Enter> UPS: (ACK
Meanings: Output current sampling value will decrease about 0.1A.
