Use of molbox ohmic  

calibration cable 

Instruction Sheet 

This cable kit has two uses related to the molbox mass flow terminal. 

1)  This kit can be used to connect the following DHI molbloc simulators: 

P/N 401233 for 100 Ohm 
P/N 401232 for 107 Ohm 
P/N 401234 for 110 Ohm 
P/N 401235 for 115 Ohm 

to a precision resistance measurement standard for the purpose of measuring the resistance values of the 
precision resistors in the molbloc simulators. This is an important part of maintaining the measurement 
traceability of the molbox Ohmic Measurement System. 

2)  This kit can be used to connect (2) precision resistance references (decade boxes, for example) to the molbox 

mass flow terminal for the purpose of calibrating the molbox Ohmic Measurement System. This is in lieu of using 
molbloc simulators for the calibration of the molbox Ohmic Measurement System. 

When using the cable to verify or measure the resistance values of the precision resistors within any of the DHI 
molbloc simulators, connect the 15-pin DSUB connector directly to the simulator connector.  There is no need to use 
the included gender changer.  The bananna plugs are then used to connect to the resistance measurement 
reference.  Use the 4-wire resistance measurement mode of the reference for a proper measurement.
