1 Introduction
The M50 is a modu ar moisture measurement system, designed for use in
environments ranging from hand-he d measurements to industria monitoring and
contro . It can be used to measure the moisture content in any non-conducting
materia .
The M50 Handset is one component in the M50 system. It is a battery-powered unit
that a ows the M50 probe to be used in portab e app ications. The handset is shown
be ow, connected an M50-P-A probe.
Two versions of Handset user interface are avai ab e. This document describes
Handset part number M50-PHP-R, as shown in the figure be ow, which disp ays a
Go/No-go indication designed for testing radomes. The a ternative user interface
shows the moisture content as a percentage of the materia 's dry weight.

1.1 Handset Features
The handset's firmware can be customised for different app ications, but this unit's
primary features inc ude:
•Moisture eve disp ayed in a graphica format, divided into 'good', 'poor' and
'fai ' categories.
•Three preset density va ues are programmed into the handset (sandwich, foam
and so id), for quick se ection by the user when working with different
composite materia s.
•Data ogging function to store readings in the handset for down oad to a PC.
•USB interface to a ow handset configuration from a computer, down oad of og
data, and recharging unit's batteries.
•Rechargeab e batteries giving up to 20 hours continuous usage from a fu
charge.
•Batteries can be recharged by p ugging the handset into a USB interface or a
mains-powered USB charger.
•The unit is designed to have a IP65 ingress protection rating1.
1.2 Packing List
The fo owing items are shipped with the standard M50 handset system:
•Handset (fitted with rechargeab e batteries).
•Docking station for recharging the batteries and communicating with a PC.
•M50 probe, fitted with cab e and hand e for connection to handset.
•Mains powered USB charger.
•USB cab e to connect the docking station to the mains charger or a computer.
•Software insta ation disk for PC software to configure the handset.
•Protective rubber boot for handset (optiona item).

1.3 Setting up the Handset and Probe
First connect the probe to the handset. The connector on the probe's cab e fits to the
screw connector on the top of the handset. It is keyed and wi on y fit one way. Screw
the connector in unti it is finger-tight. Do not use any too s to tighten the connector.
To set up the docking station for battery charging, connect the USB socket on the rear
of the docking station either to a USB mains charger or to a computer's USB port.
Then the batteries can be charged simp y by p acing the handset in its docking station,
The batteries may on y be partia y charged when the unit ships, and cou d take up to
ten hours to fu y charge.
1.4 Rep acing The Batteries
The unit ships with 3 NiMH 'AA' rechargeab e batteries with nomina capacity of
2850mAh. If the batteries need to be rep aced in the future (they are accessib e from
the underside of the handset), it is important to rep ace them with equiva ent NiMH
batteries.
The handset is configured to charge the batteries when docked in the docking station,
with a charging current appropriate to these high-capacity NiMH ce s. It is important
that the correct rechargeab e ce s be fitted. Under no circumstances fit anything other
than NiMH batteries.
Only fit the correct high capacity NiMH batteries.

2 Handset Controls
The figure be ow shows the handset's screen indicators and keypad contro s.
2.1 Screen Indicators
The indicators abe ed A to F in the above figure have the fo owing meanings.
2.1.1 Indicator A – Battery Leve Indicator
The battery indication shows the charge remaining in the batteries. Norma y the
disp ay is green, but when the charge drops be ow about 25% the co our changes to
orange.
The unit is recharged by p acing it in the docking station, which can be p ugged into a
mains-powered USB charger or into a computer's USB port. In either case the unit wi
draw power over the USB connection to charge the batteries. When the battery is
charging the indicator shows an animated disp ay in a oop where the battery eve
rises from zero to fu y charged.

When the handset is connected to an externa power source it wi beep to confirm that
it has externa power. If the unit is switched off when it is docked then it wi turn on
the LCD at ow intensity to provide an indication of the battery charging status. If the
unit is removed from the dock it wi beep again and switch off.
2.1.2 Indicator B – Condition Summary
The handset shows a summary of the condition of the materia current y being sensed
by the probe. If the moisture content is be ow 2.9% it is f agged as 'good', between
2.9% and 5.0% it is f agged as 'poor', and above 5.0% it is 'fai '.
2.1.3 Indicator C – Number of Data Log Points Avai ab e
The handset a ows up to 64 data points to be ogged in its memory for down oading to
a computer over the USB interface. This item shows the number of data og points
that remain unused in the handset.
2.1.4 Indicator D – Auto Switch Off Timer
The handset provides a feature to automatica y switch off the handset after a period
of inactivity. When this feature is enab ed a T symbo is shown on the screen. When
the feature is disab ed (the factory defau t) there is no symbo present in this ocation.
2.1.5 Indicator E – Density Setting
The handset contains three preset configurations of materia density, and this
indicator disp ays which preset is in use. The factory defau t provides settings for
sandwich, foam and so id composite materia s.
2.1.6 Indicator F – Bar Graph
This provides a graphica indication of the moisture content of the samp e under test.
The numbers and sca e underneath the bar graph show the moisture reading as the
percent moisture content by weight of the samp e under test. It is ca cu ated using
the fo owing formu a:
Percent Moisture =Weight moist −Weight Dry
Weight Dry
×100
The moisture reading depends on the dry weight of the materia , which is configured in
the handset by se ecting one of the presets (Section 3.2 describes how to do this).

2.1.7 Indicator G – Error Status
In norma operation the top eft of the screen is b ank. In the event of an error
condition this space is used to report the prob em. In Figure 2 above the warning
means that the handset cannot communication with the probe (e.g. because it is
disconnected).

functions.
2.2.1 Button 1 – Power key
This key is used to switch the handset on and off. Press this key once to switch on the
handset. At start-up a sp ash screen is disp ayed showing the unit's part number and
seria number, whi e a power-on se f-test is performed. Once the start-up tests have
comp eted, this key can be pressed again to switch the unit off.
The unit supports an automatic power-down faci ity, set via a configuration menu (see
Section 3.1). This is provided to minimise battery usage in the event the unit is
accidenta y eft switched on. The factory defau t is for the unit to remain switched on
indefinite y.
2.2.2 Button 2 – Right Arrow Key
This key is used to scro through the preset density settings. Each time the key is
pressed the next avai ab e preset is se ected. When the handset reaches the end of
the ist of presets it wi then return to the first preset in the ist.
When navigating menus this key is used to activate the next sub-menu in the menu
hierarchy.
2.2.3 Button 3 – Down Arrow Key
In the norma disp ay mode this key is used for one-touch data ogging. Each time the
key is pressed the current moisture measurement and handset configuration is ogged
in memory. Up to 64 such data points can be recorded in the handset. This data can
be down oaded to a PC and stored to disk, and the og is a so c eared under contro of
the PC interface. See Section 4.2.2 for detai s.
When navigating menus this key is used to scro through the menu items in the active

The four arrow keys on the keypad can then be used to navigate through the menus
and configure the handset. Pressing the Menu key at any time when the menus are
disp ayed wi return to the main disp ay screen.
The top- eve menu has sub-menus to contro or view the fo owing:
•LCD back ight brightness
•Automatic switch-off of the instrument
•Settings for the handset key-c icks and buzzer
•System version information
The high ighted menu item in the active menu can be changed using the Up- rrow
