First Startup
1. Check that the 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. The meter will then ask if
you want to change the following settings:
- Units
- Date
- Time
If you answer
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 30.
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.
