CLK /LOCK for use as an auxiliary unit in a clock and lock system or
to STAND for use as a stand alone unit.
CLK /LOCK Fixed on master (-LK M ) unit configuration in a clock and lock
system. Power up with EX T (external) clock mode on unit with –LK S
option. (See OPTION menu section.).
Note that this field cannot be changed if the –LK M option is
installed.
The frequency resolution below 81.9 Hz in M A ST clock and lock
mode is reduced to 0.1 Hz from the normal 0.01 Hz.
Sets the A uto Level Control (A LC) mode. This mode uses the internal measurement
system to zero regulate the output. There are three modes of operation:
OFF No measurement-based output regulation.
REG Output regulation is enabled. AC source will continuously regulate output but
will not trip off output.
ON Output regulation is enabled and output will fault (trip off) with Error 801
"Output V oltage fault" if regulation cannot be maintained and the programmed output
voltage is 10V rms or higher. No error is generated for settings below 10 volts.
In most situations, the A LC mode should be set to REG or ON for optimal performance.
Note: The A LC mode only functions for programmed output voltages above 10 V rms.
Selects programmable output impedance. The A LC mode must be turned off for the
programmable impedance to be turned on. This function allows you to change the
output impedance (R and/or L) of the power source.
Selects SINGLE or THREE phase mode of operation. The M X 15 models operate only in
single-phase mode so this field will always show N/A (not applicable).
Selects the start phase angle for output changes made to either voltage or frequency.
This allows changing the output at a specific phase angle. The ON/OFF key also uses this
phase angle setting to program the output voltage up to the set level after the output
relay is closed. The default value for this field is RA ND. To set the start phase angle, set
the cursor to the ST PHA SE field and use either shuttle knob or the keypad to adjust
between ± 360°. To set to RA ND, use the BACK key.
