Sets or reads "latch" status of the LOW limit

LOL
(LOW LIMIT)

Sets or reads the LOW limit value

MVV
(MV/V CALIBRATION)—
Model 3570 only)

Sets or reads the input sensitivity

TRR
(TARE REGISTER)

Sets or reads the tare register value

ZRO
(ZERO)

Sets the zero offset ("b" term) so that the existing input yields a specified reading; there is no valid "read" form of the command
