Functional description
Microprocessor-based and equipped with a large measured-value memory, the MD 3150 is
optimal for:
• Automatic temperature monitoring
Measured values can be logged and saved automatically in free programmable time
intervals.
• Verification of temperature control settings
e.g., for heating or refrigeration systems, air conditioners, food chill systems,
temperature-sensitive technical equipment, etc.
Data can be read out, processed and logged in a PC.
• Comparative measurement of two temperature values (MD3150)
If two temperature sensors are connected, two temperature values can be compared with
each other, e.g., room temperature and temperature in the feeding line from the heater.
Temperature measurement: Press the ON/OFF key to switch on the device
Mode functions: Press the Mode key a the +/- keys as needed
Switching off: Press the ON/OFF key once more.
The following data is restored when the device is switched on:

Operating modes
Mode 0: Temperature indication and interface output
Mode display Small display Large display
0 Current temperature
The current temperature value is displayed in this mode.
In addition, temperature values can be output via the serial interface in this mode. A
condition is that the small display is 'ON' in mode 1 of the device.
If the measurement is taken on-line, note that the automatic switch-off function 'AoFF'
is 'OFF' in mode 7 of the device.
Only MD3150:
Press the plus key to select the required measuring channel.

Mode 2: Set time interval
Mode display Small display Large display
2 Time interval in seconds
The measuring interval can be set between 1 and 9999 seconds. At the end of the
set interval the next measured value is stored in the memory automatically (max. 800
measured values).
Pressing the plus key increments the time interval, the minus key decrements it.
Keeping a key pressed automatically increments / decrements the time interval (auto-
increment). Time intervals > = 64 sec. enable the power save mode when a
measuring series is started in mode 3.
Mode 3: Interval measurement
Mode display Small display Large display
3 End,StP,memory loc. no. Current temperature, HLt
If no interval measurement is active, the small displays shows ‘End’ and the large
display shows the current temperature value.
Pressing the plus key starts an automatic interval measuring mode provided an
interval timer > 0 has been entered in mode 2.
The small display always shows the current memory location number whereas the
large display shows the temperature value for that location.
Pressing the minus key stops the interval measurement. In this case the small display
shows ‘StP’. Pressing the plus key again continues the measurement in intervals. If
the measured value memory is full (800 values), the interval measurement stops
automatically. The active interval measurement also stops when the minus key is
pressed twice. The small display shows ´End´.
If a trigger function is active in mode 7 and an interval measurement is started, bars
are displayed in the top or bottom segment row (small display) as long as the trigger
temperature (mode 6) has not been reached. The actual interval measurement starts
only when the trigger temperature set in mode 6 is reached (actual temperature value
above or below the trigger).
If the mode is changed while an interval measurement is active, mode 4, mode 8,
mode 0 and mode 1 are not available. If the interval measurement is interrupted,
mode 8 and mode 0 are skipped. The min, max and mean value memories are
deleted after the interval measurement is started.
Power save mode:
If a time interval of > 64 seconds is set in mode 2, the measuring instrument changes
to power save mode after the measured value is stored. The large display shows
´HLt´. The measuring instrument is activated again just before the next measurement
and returns to power save mode again after the measurement (power consumption in
power save mode is approximately 1mA).
The power save mode (´HLt´) can be exited by holding the minus key pressed. This
also automatically stops the interval measuring mode.
During long-term measurement the series can only be stopped (small display = ‘StP’)
at the time the measured value is saved in the memory.

Mode 4: Display interval-measured values.
Mode display Small display Large display
4 Memory location no. Temperature
Pressing the plus / minus keys displays the temperature values of the last-saved
series. The small display shows the memory location number and the large display
shows the temperature value at this location.
Holding the plus/minus key pressed automatically increments/decrements the
memory location number (auto-increment).
If an interval measurement is active (mode 3), mode 4 is skipped.
Mode 5: Display min, max, mean values
Mode display Small display Large display
5 0 : Min, 1 : Mean, 2 : Max Tmin , Tmean , Tmax
Pressing the plus key shows 0, 1, 2 in the small display.
The large display shows the appropriate minimum, mean and maximum, temperature
values. These memory entries are automatically deleted when the next interval
measurement is started (mode 3).
The above 3 values can be deleted manually with the minus key.
In this case the values -20°C , 0°C , +120°C (MD3150) resp. –200°C,0°C,1150°C
(MD3060) (measuring value limits) appear at these 3 locations.
Mode 6: Set trigger threshold
Mode display Small display Large display
6 Trigger threshold (temp.)
The trigger threshold (temperature value at which an interval measurement is started
when the set value is exceeded or undershot in mode 3) can be set with the
plus/minus key. To facilitate the setting, this setting has auto-increment feature (keep
key pressed).

---, --- / On,OFF t r i g / A o F F
Pressing the minus key alternates between entry of 'trigger conditions' and 'automatic
switch-off' of the device.
Setting trigger condition: The large display shows ‘t r i g’
The 3 available trigger conditions are selected with the plus key:
- OFF
- top segment bar:
- bottom segment bar:
Interval measurement starts directly in mode 3.
Interval measurement starts if the temperature set
in mode 6 is exceeded.
Interval measurement starts if the temperature set
in mode 6 is undershot.
Setting the device for switch-off: The large display shows ‘A o F F’
The device switch-off function can be selected with the plus key.
- OFF Automatic switch-off function is disabled
- On Automatic switch-off function is enabled, i.e., if the device does not
detect activity within 4 minutes, it switches off automatically.
Mode 8: Manual save
Mode display Small display Large display
8 Memory location no. Current temperature
The current temperature and the memory location number are displayed.
To carry out a series of measurements in manual save mode, a memory reset to
´000´ must at first be made with the minus key. Each press of the plus key saves the
current temperature value at the indicated memory location (small display).
If the measured value memory is reset but no manual saving carried out, the previous
series is not deleted, it will be deleted when a manual save is carried out.
More values can be added to an available series of measured temperature values in
manual save mode. For this, display the last-saved temperature value in the series in
mode 4 and then change to mode 8.
Pressing the plus key saves the current temperature value at the next memory
location.
Only MD3150 :
The current temperature value corresponds to the measuring channel selected in
mode 0. If 2-channel measurement mode is selected in mode 0, wait at least 2
seconds between 2 measurements in manual mode.
Please note:
Values entered in manual mode are only saved permanently when mode 8 is exited
and mode 0 adopted.
