maintaining the product.
Product Related Safety Precautions
The MM70 delivered to you has been tested for safety and approved
as shipped from the factory. Note the following precautions:
WARNING
CAUTION
Ground the product, and verify outdoor installation grounding
periodically to minimize shock hazard.
Do not modify the unit. Improper modification can damage the
product or lead to malfunction.
ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage
to electronic circuits. Vaisala products are adequately protected
against ESD for their intended use. However, it is possible to damage
the product by delivering electrostatic discharges when touching,
removing, or inserting any objects inside the equipment housing.
VAISALA________________________________________________________________________ 5
USER'S GUIDE____________________________________________________________________
To make sure you are not delivering high static voltages yourself:
- Handle ESD sensitive components on a properly grounded and
protected ESD workbench. When this is not possible, ground
yourself with a wrist strap and a resistive connection cord to the
equipment chassis before touching the boards. When neither of the
above is possible, at least touch a conductive part of the equipment
chassis with your other hand before touching the boards.
- Always hold the boards by the edges and avoid touching the
component contacts.

CHAPTER 3
INSTALLATION AND MOUNTING OPTIONS
Installing and Recharging the Batteries
1. If you are using alkaline batteries, unscrew the back plate of the
indicator and insert the alkalines. If MM70 is ordered with
rechargeable battery, it is already in place as shipped from the
factory.
2. Recharge the battery as follows: Plug in charger connector to the
indicator. The plug is located at the top of the indicator, covered
by rubber seal. Then connect the charger to wall socket. A
battery symbol in the left corner of the display starts to roll.
3. It is not recommended to use MM70 during the first recharging.
Later on MM70 can be used while recharging.
4. Duration of recharging depends on the charge level of the
battery being 4 hours typical. The recommended first recharging
time is 6 hours.
5. The battery is full when the battery symbol stops rolling.
6. Disconnect the charger.
Turning On the Device
1. Connect the probe to either one of the bottom connectors of the
indicator. To ensure durable connection, screw the metal ring
clockwise until it tightens up. (Respectively, when
disconnecting the cable, first screw the metal ring
counterclockwise until it loosens and then pull out the plug.)
VAISALA_______________________________________________________________________ 13

2. Press the power on/off key.
3. Select the language by using the arrow up/down keys. Confirm
by pressing the SELECT key. You can select the language later
on, as well. For more information, see Selecting Language on
page 27.
4. To change the date, select Date and press the SET key. Change
the date by using any of the arrow keys: up/down/left/right. To
confirm the date, press the OK key. The default date
presentation format is: year-month-date. If you want to change
the format, see Setting Date and Time on page 28.
5. To change the time, select Time and press the SET key. Change
the time by using any of the arrow keys. To confirm the time,
press the OK key. The default time presentation format is 24hour clock. If you want to use 12-hour clock, select 12-hour
clock, and press the On key.
6. Press the EXIT key. To check and change the pressure setting,
select YES. Otherwise select NO, basic display appears.
Installing the Probe
First select a place for the probe that simulates real conditions of the
process. Oil should circulate freely around the sensor; a rapid oil flow
is recommended. Install the probe directly into the circulation system
and not into the oil reservoir because of deposition.It is recommended
that the sensor head is installed directly in the process through the ball
valve assembly. When the ball valve assembly is used, the pipe does
not have to be emptied or shut down for installation or removal of the
probe. Install the sensor head transversely against the direction of the
process flow. Avoid installing into a bend in the pipe.
NOTE
Take care not to damage the pipe of the probe. If the pipe is damaged,
the probe head is less tight and will not go through the clasp nut.
Make sure that the filter is tightly fastened to protect the sensors..
Mounting the Probe for Pressurized Pipelines/Oils
Due to the sliding fit, the MMP78 is easy to install into and remove
from the pressurized process. The probe is especially suitable for the
14 __________________________________________________________________ M210878EN-A
Chapter 3 ____________________________________ INSTALLATION AND MOUNTING OPTIONS
measurements in pipelines. The maximum installation pressure is 10
bar and the maximum operation pressure is 20 bar.

Tightening the Clasp Nut
1. Adjust the probe to a suitable depth according to the type of
installation and tighten the clasp nut first manually.
2. Tighten the clasp nut first manually. Mark the fitting screw and
the clasp nut. Tighten the nut a further 30 - 40° (ca.1/12" turn)
with a plastic wrench. If you have a suitable torque spanner,
tighten the nut to max 35±5 Nm (25±4 ft-lbs).

Take care not to over tighten the clasp nut to avoid difficulties when

When the probe is used in a pressurized processes the sensor head
should preferebly be installed through a ball valve assembly.

CAUTION
CAUTION
In pressurized processed it is essential to tighten the supporting nuts
and screws very carefully to prevent loosening of the probe by the
action of pressure
Take care not to damage the probe body. A damaged body makes the
probe head less tight and may prevent it from going through the clasp
nut.
Ball Valve Installation
The ball valve installation is preferred when connecting the probe to a
pressurized process or pipeline. Use the Vaisala BALLVALVE-1 ball
valve set or a 1/2" ball valve assembly with a ball hole of 14 mm or
more. If you install the sensor head ( 12 mm) in a process pipe, please
note that the nominal size of the pipe must be at least 1 inch (2.54
cm). Use the manual press tool to press the sensor head into the
pressurized (< 10 bar) process or pipeline.
0605-083
1. Shut down the process if the process pressure is more than 10
bars. If the pressure is lower there is no need to shut down the
process.
2. Make the installation according to the figure below. Install the
sensor head transversely against the direction of the process
flow.
VAISALA_______________________________________________________________________ 17

3. Make sure that the temperature at the measurement point is
equal to that of the process, otherwise the moisture reading may
be incorrect.

Chapter 3 ____________________________________ INSTALLATION AND MOUNTING OPTIONS
NOTE
The probe can be installed in the process through the ball valve
assembly provided that the process pressure is less than 10 bars. This
way, the process does not have to be shut down for installing or
removing the probe. However, if the process is shut down before
removing the probe, the process pressure can be max. 20 bars.
Mounting the Probe for Direct Measurement (No Pressure)
1. Lift up the clasp nut, see picture below.
2. Install the probe into measuring position. When stopping the
measurement, pull down the clasp nut to clean the probe or just
wipe the probe with soft cloth.
