6 HM680 Hydronic Manometer
FLOW
Pressing the
FLOW
key from the Pressure Measurement screen provides access to the Flow
Measurement screen.
Powering the Instrument
The HM680 Hydronic Manometer is equipped to be powered either by four (4) AA-size batteries
(alkaline or rechargeable NiMH) or the AC adapter.
Using the AC Adapter
The AC adapter allows the HM680 Hydronic Manometer to be powered from a standard AC wall outlet.
When using the AC adapter, the batteries (if installed) will be bypassed. The AC adapter also charges the
NiMH type batteries (if installed) in the unit.
Note:
With the battery-type selection switch set to NiMH, the manometer will initiate charging the
batteries whenever the AC adapter is connected.
Installing the Batteries
To install/replace the batteries:
1.
Turn the manometer off and locate the battery cover on the back of the unit.
2.
Loosen the screw on the battery compartment cover and lift to remove.
3.
Remove the battery holder. Tapping the backside of the meter against your hand may assist in
removing the battery holder.
4.
Remove the old batteries and replace with fresh batteries (alkaline or rechargeable NiMH). Ensure
that the batteries are correctly oriented within the battery holder.
5.
Set the battery-type selection switch to indicate the type of batteries to be used (alkaline or
rechargeable NiMH).
