Field Entry:
The Vibration Exciter Control Type 1053 has two multi-digit LED dis-
plays, which display the instantaneous value of any generator, com-
pressor or vibration-meter parameter chosen using the appropriate
key. Pressing a parameter key, when the instrument is in stand-by
mode, enables use of the field entry system (keyboard or thumbwheel)
for setting the selected parameter value. The 1053 includes a memory
for storing four complete test-programmes (front panel settings) with a
sequential set-up guide for the selected front panel.
A thumbwheel for adjustment (up or down) of the selected parameter
value indicated on the associated LED display. The adjustment sensi-
tivity of the thumbwheel is automatically set to be compatible with the
selected parameter range.
A keyboard consisting of the numerical keys ("0"
to
"9", "·" and
"CLR"), and the four ENTER keys. The numerical keys are used to set
the numerical value of the selected parameter, in the Echo field (on the
generator display). Once a value has been selected, the Echo LED on
the generator display will flash.
The "CLR" key is used to clear the echo field. Alternatively the
thumbwheel can be used to delete all but the first digit of the numeri-
cal value, or to increase the value by factors of ten.
