First Startup
1. Remove the yellow transport protection cap from the HMP40S
probe, and connect the probe to the HM40 indicator.
2. Open the battery cover and insert two AA-size batteries.
3. Close the battery cover and turn on the HM40 by pressing the
Power button. If the HM40 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 indicator 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 HM40 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 44.
NOTE HM40 indicator will retain the date and time even during battery
changes. The clock will have to be set again only if the indicator is
without battery power for several hours.
