Use of molbox ohmic
calibration cable
P/N 402150
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.
CABLE USE FOR VERIFICATION OF MOBLOC SIMULATORS
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.
