It can be reached in one of two ways:entry in the MENU screen and pressing the ENTER keyn the FUNCTION keypadchange output parameters. The most commonly usedparameters are all located in PROGRAM 1. The PREVIOUS SCREEN entry, when selected, willreturn the user to the most recently selected menu. This is normally the MENU screen unlessted using the PROG key on the FUNCTION keypad. Lesslocated in PROGRAM 2, which can be reached from theORE selection, or by pressing the PROGRAM key twice.PROGRAM 1VOLTAGE Programs the output voltage in Vrms while in AC mode orabsolute voltage when in DC mode. In DC mode, negativevalues can be entered.FREQ Programs the output frequency when in AC mode. If the unit isin DC mode, the value for FREQ will be set to DC and cannotbe changed until AC mode is selected. When in AC mode, thefrequency can be changed from 16 Hz to 500 Hz. Valuesentered that fall outside this range will generate a -200 RANGEERROR and will not be accepted.VOLT RANGE Selects 150V, 300V or optional 400V range in AC mode and200V or 400V range in DC mode. The actual range values maybe different depending on the configuration. The value of thisfield can only be changed with the shuttle or the +/- key.CURR LIMIT Sets the current limit value for the current detection system.When the load current value exceeds the set current limit, afault condition is generated. The actual response of the ACSource to a current limit fault is determined by the protectionmode selected in the CONFIGURATION menu. (CC = ConstantCurrent, CV = Constant Voltage).PROGRAM 2PHASE Selects the phase angle between the external clock and theoutput of the AC source. If the clock source is internal, thisparameter has no effect.MX Series 85
