Maintenance 

5.1    Replacing the battery 

To replace the battery, turn the latching button counter-clockwise and pull out the battery holder.  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

5.2    Service cable 

  Cable AC3006 converts UART (service connector) to USB and is used to connect the HP22 to a USB port 

of a PC running the ROTRONIC HW4 software. Prior to using this cable, the ROTRONIC USB driver must 
be installed on the PC.  Both the driver and the installation instructions (document 

E-M-HW4v2-Main

) are 

located on the HW4 CD. 

  As an alternative, cable AC2001 is used to connect the HP22 to a probe input of the HP23 hand-held 

calibrator. For service purposes, the HP23 offers essentially the same functionality as the HW4 software. 

 

5.3    Location of the service connector (mini USB type) 

 
 

WARNING

: the service connector is a UART 

interface with a mini-USB connector type. Do not 
connect the service connector directly to the USB 
port of a PC or hub. 
 
The service connector (UART interface) can be 
accessed without opening the enclosure after 
removing the protective red round cover.
