User manual DHI USE OF MOLBOX OHMIC CALIBRATION CABLE PN 402150

[. . . ] Use of molbox ohmic calibration cable P/N 402150 Instruction Sheet This cable kit has two uses related to the molbox mass flow terminal. [. . . ] 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. 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. Figure 1 Cable use with DMM CABLE USE FOR MOLBOX OHMIC SYSTEM CALIBRATION When using the cable to apply a known resistance value to the molbox, the included gender changer will be required. The bannana plugs are used to connect to the decade boxes as shown in Figure 2.
