on sequence this key allows entry to the setup mode so that the calibration coefficients of the transducers
can be entered and stored.
CH NO / ‘–‘
- In the number entry mode it is used to enter the minus sign. In measurement mode it is
used to select the transducer number (channel number) whose reading is being measured, or has to be
stored or recalled.
ESC / CE
- In the number entry mode it is used to clear an erroneous entry. The whole number entered
earlier is erased; it is not possible to erase any single incorrect digit. In all other modes it is used to
terminate an unwanted command which may have been erroneously selected or activated.
ENTER
- In the number entry mode it signals the indicator that the number entry is complete and the
value can be accepted by the indicator. In all other modes it is used as a confirmation key whenever
prompted by the display to do so.

assigned to each number key is displayed on the display as soon as the key is pressed. To accept the
displayed units the ‘ENTER’ key has to be pressed. The assignment of symbols is as follows:
Key 0 =
mm
milli metres
Key 1 =
m
metres
Key 2 =
tf
tons
Key 3 =
kN
kilo Newtons
Key 4 =
kPa
kilo Pascal
Key 5 =
Mpa
Mega Pascal
Key 6 =
