Save parameters in the measuring unit
Setting the "Configuration Jumpers" can protect the parameters on the measuring unit computer witch was
loaded by using the software RGC 3000. This configuration Jumper is on the mainboard (see fig. 2-6). If the
jumper is set, the parameters inside the measuring unit cannot be override.
Changes in the parameters can only be transferred to the measuring unit, if the jumper is not set. The setting
of the jumper can be checked on the display of the “instrument status” page. See Section 3.2 of the software
manual. How to set the jumper is shown in Figure 2.6.
