Instruction SONOMETER™ 1100
Once the meter has been installed, the components (calculator, vol-
ume measuring component and both temperature sensors) must be
sealed and the meter taken into operation.
Bleed the system until the ow rate display is steady.
Check the display for a plausible indication of ow rate and
temperatures.
6.0 Start-up operation
The energy meter has two slots for expansion modules. The modules
can be used and combined as shown in the table. The analogue mod-
ule needs both slots. Integrated radio is always possible. The analog
module occupies both positions.
7.1 Installation of modules
1. Open the calculator by releasing the side fasteners
2. Lock the module into the appropriate slot and carefully connect
the pre-formed ribbon cable at both ends.
3. Close the lid and check the meter for correct operation by pressing
the push button (loop 3). Renew the seal of the housing lid if the
meter functions correctly.
The relevant ESD regulations (electrostatic discharge) must be
observed.
No liability is accepted for damage (especially to electronic circuits)
resulting from failure to comply with the ESD regulations.
These modules have no eect on consumption recording and can
be tted retrospectively without damaging the verication mark.
