KEYPAD FUNCTIONS - MODEL 200 and 205
The Model 200 and 205 are equipped with a 7-key keypad. The keypad is used to enter
commands and data into the instrument. This section describes each key along with its normal
function. It is helpful to refer to the actual instrument while reading this section.
The membrane keypad is not to be operated with pointed objects (pencils, pens,
fingernails, etc). Damage to keypad resulting from this practice is NOT covered
under warranty.
ON/OFF KEY
This key performs two functions. Pressing it when the indicator is off will apply power to the
instrument. If the indicator is already on, pressing this key will turn the indicator off.
ZERO KEY
Pressing this key will cause an immediate zeroing of the weight display up to the selected limit of
4% or 100% of the scale's capacity. This selection is made during the setup and calibration of the
instrument. Note that the indicator will not respond to this command unless the weight display is
stable.
TARE KEY
Pressing the TARE key alone will cause the current gross weight to be stored as the new tare
weight and cause the weight display to change to the net weight display mode ( Net annunciator
will turn on).
NET/GROSS KEY
This key is used to toggle between Net and Gross weight modes. The selected mode is indicated
by turning on the appropriate annunciator on the display. Note that if no valid tare weight has been
entered, pressing this key will cause a momentary "notArE" display error and the indicator will
remain in the Gross weight mode.
