5.10 Auto Power Off
The gauge features an Auto Power Off function designed
to conserve battery’s life. If the hardness tester is idle
(neither measuring nor any key operation) for 5 minutes, it
will turn itself off. Before, the LCD display will continue
flashing for 20 seconds. Exept the
key, any key can be
pressed to stop the twinkle of the LCD display.
Like this, the operation of powering off at the moment can
be interrupted.
While the voltage of the battery is too low, <E00> will be
displayed. Then the gauge is automatically powered off.
5.11 Battery Replacement
Two AA size Alkaline batteries are necessary as power
resource. After several hours’ usage, the battery symbol
on the screen will be shown as
. The less dark parts
are indicated, the more close to be filled. When the
capacity runs out, the battery symbol will be shown as
and the symbol will begin to flash. Now batteries
have to be replaced.
Pay attention to the polarity of the batteries!
The batteries have to be taken out if the instrument
hasn’t been used for a longer period of time.
5.12 Connection to PC
The hardness tester HMO is equipped with a RS-232 serial
port. Using the accessory cable (the cable and following
referred software are optional parts) the gauge has the
ability to get connected to a computer or external storage

the provided nylon brush. When cleaning the
guide tube, the support ring has to be
unscrewed first. Then the impact body has to be
taken out. The nylon brush has to be spiralled in
counter-clock direction into the bottom of the
guide tube. It has to be taken out and repeated
for 5 times. At last, the impact body and the
support ring have to be installed again.
The impact body has to be released after use.
Any lubricant is absolutely prohibited inside the
impact device.
6.2 Instrument Maintenance Program
* If the standard Rockwell hardness block is used to test
and if all the error is bigger than 2 HRC, the ball top of the
impact device or the impact object may have to be
changed. The invalidation may be caused by abrasion.
* If any other abnormal phenomena appear to the
hardness tester, nothing may be dismantled or any fixed
parts may not be adjusted by the user himself.
The warranty card has to be filled in and sent to SAUTER
GmbH. The warranty service will be performed within a few
working days.
6.3 Fault Analysis & Clearance
6.4 Note of Transport and Storage Conditions
