First Startup
1. Check that the HMP110 probe is securely attached
and remove the yellow transport protection cap from
the probe.
2. Open the battery cover and insert two AA-size
batteries.
3. Close the battery cover and turn on the meter by
pressing the Power button. If the meter does not turn
on, check the battery orientation. Replace the
batteries with fresh/recharged ones if needed.
Initial Settings
When you power on the HM40 for the first time (or
after a factory reset of the settings), you must first
select the operation language. You will then be asked if
you want to change the following settings:
-Units
-Date
-Time
If you answer Yes to the question (recommended), the
meter will show the settings screens before showing
the measurement view. Use the arrow and function
buttons to select. For more information, see section
Settings Submenu on page 22.
HM40 will retain the date and time even during
battery changes. The clock will have to be set
again only if the meter is without battery power
for several hours.
