Fig. 2. 1. Vibration Exciter Control Type 1050 - Front Panel
The Vibration Exciter Control Type 1050 has two multi-digit LED dis-
plays. These provide an instantaneous read-out of the value of any
generator, compressor 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 (keyboard or thumb-
wheel) to set the selected parameter value. The 1 050 includes a memo-
ry for storing 4 complete test programmes (control panel settings) with
a sequential set-up guide for the selected Front Panel.
2.1.1. Measurement Set-up Controls
Field Entry: 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 selected parameter numerical value in the Echo field (on the gener-
ator 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 thumb-
wheel can be used to delete all but the first digit of the numerical
value, or to increase the value by factors of 10.
