CLOCK/LOCK 

Indicates the presence of the -LKS clock and lock auxiliary 
option.  For units without -LKS, this field is set to N/A. For units 
with the -LKS option installed, this field is set to ON.  Note that 
master unit (with -LKM) also has this field set to N/A. 

WH METER 

Indicates the presence of the Watt Hour Meter option.  

SYSTEM 

Shown here on Series I models only. See CONFIGURATION 
SETUP 3 screen below.  

CONFIGURATION SETUP 3 

(Series II models only) 

MS704 

Indicates the presence of the MIL/STD-704 Revision A through 
F test option. If this option is installed, this field will show ON. If 
this option is not installed, this field will show N/A (not available). 
This field is available on Series II MX systems only. 

ABD 

Indicates the presence of the ABD0100.1.8  test option. If this 
option is installed, this field will show ON. If this option is not 
installed, this field will show N/A (not available). This field is 
available on Series II MX systems only. 

LF 

Indicates the presence of the Low Frequency limit option. If this 
option is set, the maximum frequency that can be programmed 
is 500 Hz. This field is available on Series II MX systems only. 

SYSTEM 

This field sets the controller for the correct MX system 
configuration. Available settings are: 
MX30 

MX30 Single Unit 

MX45 

MX45 Single Unit 

MX60 

MX60 system Master 

MX90 

MX90 system Master 

MX135 

MX135 System Master 

MX180 

MX180 system Master 

MX225 

MX225 system Master 

MX270 

MX270 System Master 

AUX Auxiliary 

System. 

If this field is set incorrectly, the current limit scaling and current 
measurement will be off by a factor of three. Changes made to 
the SYSTEM field will not take effect until 

AFTER

 power on the 

MX system is cycled. (Off, the back on). 

Note: MX systems with Firmware rev. less than 4.0 do not 
support MX60 configuration and uses MX45 setting for MX30.

 

MB 

Indicates the presence of the Multi-box option. If this option is 
set, the SYSTEM field (above) can be changed to 
accommodate reconfiguration of the MX system. If this option is 
not set, the SYSTEM configuration is fixed and cannot be 
changed by the user. This field is available on Series II MX 
systems only. 

NOTE:  If the MB option is enabled, great care MUST be taken to set the correct SYSTEM 

setting for the configured hardware. Failing do so will result in incorrect operation 
of the MX system and could even result in damage of MX or the equipment under 
test.
