BASIC CONFIGURATION
0 XING/BASED - pressing the knob will toggle
between zero crossing and zero based output
waveforms. Select zero crossing when the
instruments you are calibrating require a
waveform that has both positive and negative
peaks that are centered around zero. Select zero
based when the instruments you are calibrating
require only positive signals.
Note: To simulate negative only signals select
zero based and connect the red lead to the
ground and the black lead to the input connection
of the instrument being calibrated.
Press and release the MENU or STORE/CLEAR Key
to save your selection.
EZ-CHECK - pressing the knob will toggle
between ON and OFF. Select ON to have the
highest and lowest measured frequencies
recalled by moving the EZ-Check switch on the
side of the calibrator to HI or LO. Select OFF and
the currently measured freqency will be
displayed regardless of the position of the
EZ-Check switch.
Press and release the MENU or STORE/CLEAR Key
to save your selection.
SINE/SQ - pressing the knob will toggle between
SINE and SQ. Select SINE when the instruments
you are calibrating require a sine wave and SQ
when the instruments you are calibrating require
a square wave or pulse input.
Press and release the MENU or STORE/CLEAR Key
to save your selection.
BASIC CONFIGURATION - pressing the knob
will restore the 541 to the basic configuration
with factory defaults as shown in the menu
diagram. Output values stored in the EZ-Check
HI and LO positions are not changed.
Press and release the MENU or STORE/CLEAR Key
to save your selection.
Note: All settings are remembered even with the
power off. Removing the batteries resets the
configuration to factory defaults (Basic
Configuration) and resets the EZ-Check HI and
LO outputs to factory values.
