Congratulations on your purchase of a new Serviceman
Meter from Parker! You should find this training manual
useful as you learn how to use your newest diagnostic tool.
Getting started
What are the capabilities of my new meter?
You must first determine which level meter you have purchased. To do this please look at the
face of your meter and compare it to the following pictures.
LEVEL 1 LEVEL2
(SCM-150-1-01) (SCM-150-1-02)
Take time to notice the level two Serviceman has two additional ports on its face (arrows point
to them in the figure). These are for recharging the Ni-cad battery and exporting data to a PC or
printer. If you have purchased a level one Serviceman you do not need a recharging port as your
meter uses a standard alkaline battery.
Now that we have determined which meter you have purchased we may determine its
capabilities. Please view the Serviceman feature matrix below to determine your meters
capabilities.

Setting Your Units
When you first receive your meter its units are all set to metric. If you need to change any of the
units please read the following set of instructions:
1. Turn your meter off.
2. Depress the ÒRESETÓ key and hold it down.
3. While holding the reset key down turn the meter on by depressing the ÒON/OFFÓ key.
4. Release the ÒRESETÓ key and ÒON/OFFÓ key after 5 seconds.
5. Your LCD screen should look like this (the LCD screen is the clear rectangular portion at the
top of the meter).
6. Press the ÒMINÓ and ÒMAXÓ keys and notice how the pressure units change on the LCD
display from PSI to bar.

7. When the desired pressure unit is displayed on the LCD screen press the ÒHOLDÓ key to
save that unit type.
8. The meter Screen should still say unit except now it is waiting for you to select the type of
temperature units you would like to measure in. Use your ÒMINÓ and ÒMAXÓ keys to select
the desired temperature unit type and then press the ÒHOLDÓ key to save that unit type as
before.
9. Continue this same procedure until all four unit types have been selected.
10. When you are finished with the fourth type of unit (RPM of Unit/Min) the meter goes back
into a standard operating mode automatically.
*Note: If at any time you need to change the units on your meter just simply follow steps 1-10
again. You may change your units as often as you like.
Congratulations you have successfully set your meters units.

Using Your Meter
So far you have figured out how to tell which meter you have and set your units up. Now its time
to learn how to use your serviceman.
Pressure measurement
When taking a single pressure measurement with your new meter you will need the following
items:
(1) One Serviceman Meter
(2) One Pressure Transducer
1. Your meter has two four pin sockets on its face near the bottom. The one on the left is input
1 and the one on the right is input 2.
2. Your transducer has a cable attached to it that has a four-pin connector on it.
Be careful in this next step as it only connects when the boss on the connector is lined up
with the notch in the socket.
3. Plug the four-pin connector on the transducer cable into input one on the meter by screwing
the sleeve on the connector clockwise. Be sure your only turning the sleeve on the
connector.
Figure 1 Plugging in Your Transducer
4. Now connect the transducer to your hydraulic system via the coupling on the transducer (i.e.
PD, PDP, EMA)
Four Pin Sockets

5. Turn the meter on by depressing the ÒON/OFFÓ key.
Take a moment to notice the following items on your Servicemans display
IMPORTANT!
6. Since you are connected to input one make sure the input indicator reads ÒINP1Ó indicating it
is displaying input one.
7. If the display reads ÒINP2Ó depress the ÒINP1/2Ókey to toggle to input one.
*Note: When taking readings with two transducers of any type (i.e.
pressure transducer, temperature sensor, flow meter and RPM sensor) use
the ÒINP1/2Ó key to change the input your viewing on the display.
Congratulations you have successfully learned how to take a pressure
measurement.

Minimum & Maximum Pressure Recording (spikes and drops)
Your New Serviceman meter is capable of capturing any pressure spike or pressure drop as long
as it is 2 milliseconds (.002 seconds) long. This means you can capture virtually any spike in
your hydraulic system. To capture pressure spikes and drops in your systems pressure follow the
steps below.
1. Turn on your meter using the on/off key.
2. Depress the ÒRESETÓ button on your meter. This resets the internal minimum and maximum
values of your meter.
3. Run your hydraulic system until you believe the pressure spike or drop has occurred.
4. Depress the ÒMAXÓ button to view the maximum pressure the transducer has seen since you
depressed the reset button.

5. Depress the ÒMINÓ button to view the minimum pressure the meter has seen since you
depressed the reset button.
Congratulations you have successfully learned how to capture pressure
spikes and pressure dives.
Differential Pressure Measurement (Pressure Drop)
Your new meter can be used to measure pressure drop across any hydraulic component. What
doe that mean? Follow along.
To take a differential measurement you will need the following items:
(1) Serviceman meter
(2) Two transducers whose pressure ranges are the same (i.e. two 1,450 psi transducers)
*Note: If you try to perform a differential pressure measurement with two transducers that
do not have the same pressure range you will not succeed.
1. Connect the transducers into input one and input two on the meter via the four pin
connectors. If you are unfamiliar on how they connect see the section of this guide called
ÒPressure MeasurementÓ.

2. Connect your transducers across a component of your hydraulic system via the couplings on
the transducers. In the picture below the transducers a connected across a hydraulic motor.
3. Turn the meter on using the ÒON/OFFÓ button.
4. Depress the Ò∆PÓ button on the meter. The input indicator in the LCD display now shows
ÒINP1-INP2Ó indicating the display is showing you a differential measurement.
5. Your display is showing you the difference between input 1 & Input 2 (Input 1-Input 2).
*Important Note Differential measurements may be taken with any two
devices that are the same range (i.e. Two Flow Sensors, Two Temperature
Sensors, Two RPM Sensors). Once you have performed the Sections of
this manual on Flow, Temperature and RPM Sensors. You may find a use
for this in your system.
Congratulations you have successfully learned how to take a differential
pressure measurement.

Measuring with Flow Meters, Temperature Sensors, and RPM Sensors
Since all measuring (i.e. pressure, flow, temperature, and RPM) with your Serviceman meter is
similair the following abreviated sections are provided.
Flow Measurements
You need the following for taking a flow measurement with your meter
(1) One Serviceman meter
(2) One flowmeter with electronics
(3) One four to five pin cable (SCK-102-02-08)
1. Connect your flow meter (black block with openings on each end) to your hydraulic system
via the ports on both ends. Be sure the side which is stamped ÒINÓ is the inlet.
2. Connect the five pin end of the cable to the electronics (silver tube with wire coming out of it).
Notice the five pin connector only needs to be pushed into the electronics. It does not screw
in like the four pin connectors.
3. Connect the four pin end of the cable to the serviceman meterÕs input 1 socket by screwing
the sleeve on the connector clockwise. Be sure you are only turning the sleeve on the
connector.
4. Connect the electronics to the flow meter by screwing the connector to the socket in the
center of the flow meter. Just as before the boss on the connector must line up with the
notch in the socket for the connector to be properly aligned.
5. Turn on your meter on if you have not already done so.
Screw Together

6. Be sure that the input indicator on the LCD display reads ÒINP1Ó signifying the meterÕs display
is displaying input1. If it reads ÒINP2Ó press the ÒINP1/2Ó key to toggle the display.
7. Turn on your hydraulic system and monitor the display as needed.
8. Min and Max Flow values can be captured exactly the same way as described in the section
of this manual called Minimum & Maximum Pressure Recording (spikes and drops). Just use
the words flow meter wherever it says pressure transducer.
Congratulations you have successfully learned how to take a flow
measurement
Temperature Measurements
You need the following for taking a temperature measurement with your meter
(1) One Serviceman meter
(2) One Temperature Probe (SCT-150-74-08)
Your temperature sensor may be connected to your hydraulic system by one of the following two
methods:
A. Threaded into the temperature port on a flow meter that is connected to your system (This is
the port with a plug in it when you received the flow meter).
B. Threaded into a port in your hydraulic system utilizing a T in the line or other similar methods.
1. Connect the four-pin temperature probe cable to the serviceman meterÕs input 1 socket by
screwing the sleeve on the connector. Be sure you are only turning the sleeve on the
connector.
2. Connect the temperature probe to your system by one of the methods described above.
3. Turn on your meter if you have not already done so.

4. Be sure that the input indicator on the LCD display reads ÒINP1Ó signifying the meters display
is displaying input1. If it reads ÒINP2Ó press the ÒINP1/2Ó key to toggle the display.
5. Turn on your hydraulic system and monitor the display as needed.
6. Min and max temperature values can be captured exactly the same way as described in the
section of this manual called Minimum & Maximum Pressure Recording (spikes and drops).
Just use the words temperature sensor wherever it says pressure transducer.
Congratulations you have successfully learned how to take a temperature
measurement.
RPM or U/Min Measurements
You need the following for taking a RPM measurement with your meter
(1) One Serviceman meter
(2) One RPM measurement device (SCRPM-210)
You can utilize the RPM gauge to measure many repetitive motions. Some examples are given:
Shaft RPM, Pendulum frequency (swings/min), gear rpm, machine operating speed (parts/min),
etc
The are two ways you may take measurements with this device.
A. Place reflective tape on a moving object and place the RPM sensor so the light emitted by
the sensor reflects off the tape. This type of a reading will tell you how many times the tape
reflects the light back to the sensor per minute. The sensor and tape are pictured below.
B. This method utilizes an additional contact attachment (SCRPMA-001) which allows you to
touch the end of the rpm sensor to a rotating object. The RPM sensor with attachment is
shown below.
By calculating the circumference (2πr) of the rubber wheel and the circumference (2πr) of the
rotating object you can obtain a ratio which will allow you to calculate the RPM of the object

spinning. This is useful when a rotating device can not be stopped to apply a reflective decal.
The following formulas can be used when doing this calculation:

1. Connect the four pin end of the RPM Sensor cable to the serviceman meterÕs input 1 socket
by screwing the sleeve on the connector clockwise. Be sure you are only turning the sleeve
on the connector.
2. Setup the RPM Sensor with your system by one of the methods described above (one
method is shown below).
3. Turn on your meter if you have not already done so using the ÒON/OFFÓ key.
4. Be sure that the input indicator on the LCD display reads ÒINP1Ó signifying the meters display
is displaying input1. If it reads ÒINP2Ó press theÓINP1/2Ó key to toggle the display.
5. Turn on your hydraulic system and monitor the display as needed.
6. Min and Max Flow values can be captured exactly the same way as described in the section
of this manual called Minimum & Maximum Pressure Recording (spikes and drops) Just use
the words RPM sensor wherever it says pressure transducer.
Congratulations you have successfully learned how a RPM measurement.

Using a PC or Printer With Your Meter (Serviceman Level 2 Only)
PC Transfer (Level two Serviceman Only)

Setting the Transfer Rate and Print Interval of the Meter
First we must insure the meterÕs transfer rate is set accordingly for PC transfer.
1. Turn off the meter using the ÒON/OFFÓ key.
2. Press and hold the ÒPRINTÓ key down. While holding the print key down press the
ÒON/OFFÓ key. Your meters LCD screen should look like one of the following two photos:
3. If your LCD screen is displaying ÒPCÒ press ÒHOLDÓ to save this setting.
4. If your LCD screen is displaying ÒPrÓ press the ÒRESETÓ key and then press the ÒHOLDÓ
key.
5. What you have just done is set the transfer rate of the meter. If you were to leave the screen
ÒPrÓ and press the hold button you would have set the proper transfer rate for the SCPR-100
thermal printer.
6. Once the hold key has been depressed the LCD flashes the following:
This is asking you to enter a print interval. The print interval defines how often (in seconds) you
want the meter to send a min and max value to the PC (the min and max value it sends is the min
and max value the meter has seen since the last time it sent a min and max to the PC).
Confusing sentence? Yes. What it means though is that you will never miss a pressure spike or
drop in you system during a test as long as its at least 2 milliseconds long. This is the electronic
communication rate between the meter and transducers!

7. Use the ÒMINÓ and ÒMAXÓ keys to set the print interval in seconds.
8. Once the desired value in seconds appears on the LCD press the ÒHOLDÓ key to save and
resume normal operating mode.
Connecting the Meter to the PC
Now that the software is loaded and the meter is set up its time to get down to business.
1. You must first hook up which ever sensors you are going to use for the measurement (i.e.
Flow, Temperature, RPM, Pressure). See the section titled ÒUsing your MeterÓ for
instructions if you donÕt know what this means.
2. Once one or two sensors are hooked to the meter you must connect the meter to the PC via
the printer cable and PC adapter cable pictured below.
3. First hook the PC adapter cable to the printer cable as shown.

4. Connect the other end of the PC adapter cable to your PCÕs Serial Port/COM port as shown
below.
*Note: This must be the port you specified in the parameters when you set up the software. If
your computer is not labeled as to which one is which just plug it into one of them and you can
reset the parameters to allow the down load to work later.
5. Snap the small black connector onto the meters fiber optic port as shown.
