Analog Output Configuration Commands

The analog output(s) are set in the factory according to the order form. In

case you want to change the settings, follow these instructions.

NOTE

with the passive output version of HMP155.

AMODE

Use the serial line to select and scale the analog output quantities.

Connect the probe to the PC and then open the terminal connection

between your PC and the probe.

The probe needs to be in ADJUST mode for the

work. To put the probe in ADJUST mode, hold down the

ADJ button

until a green LED lights up.

NOTE

Analog output calibration is valid only for the factory settings. If you

change the analog output mode with

AMODE command, you must

continue by entering the

ACAL command, see ACAL on page 68.
