FACTS ABOUT PRISMA DI5C

TOLERANCE

Prisma DI-5C has a tolerance of
max. 1% in the range of +/- 1,000 mm and
max 2% in the range of 1,000-2,000 mm.

HOW TO ACHIEVE OPTIMUM RESULTS

An accurate measurement result can be achieved if both transducer and the
measured object (Crankshaft) are having the same temperature so that the
transducer temperature is not changed during the measurement.

If the transducer’s temperature diers from the measured object (Crankshaft)
temperature, an error value of approximately 0.002mm/°C can be experienced.
That’s why the transducer should as far as possible, be temperature-acclimatized
to the measured object (Crankshaft) temperature before starting
with the measurement.

2. HOW TO USE THE INSTRUMENT

2:1 DESCRIPTION

The importance of accurate crankshaft deection measurement can´t be enough
emphasized. The DI-5C series of instruments are designed to be both accurate, fast and
user friendly. The complete instrument set is stored in a customized carrying case which
includes Main instrument, Battery Charger, Transducer, Connecting cable, Extension
bars, Measuring tip, Program Manual and User Manual.

The DI-5C is a robust construction, however, it is also a high precision measuring
instrument and should be handled with care.

The TRANSDUCER is the measuring device and must be connected to the instrument
with the special cable, length approximately 7 m / 20 ft.

Extension bars are included in lengths of 10, 20, 40, 80 and 2 x 160 mm. The transducer
with measuring tip has a minimum measuring distance of 89 mm. The many extension
bars allow for measuring any distance between (min) 89 to (max) 565 mm. An optional
transducer for down to 60 mm web distance is available, however, the Ovality Kit
accessory cannot be used together with it.

All selections, information and value parameters shown on the display are accepted by
pressing the ’OK’ button. Change values by pressing the left < and right > arrow
buttons. Study the Flow scheme (chapter 5) carefully, it illustrates the various steps.
Each step is described in text below.

2:2 DISPLAY

The user procedures are menu based and information/values are presented in the
display window.
There are two display rows, each row has a capacity of 12 letters, numbers or blanks.
The display can be illuminated by a back light and the illumination can be adjusted in
ten steps.
When batteries go low on power, a battery indicator
shows the need for charging.
For battery charge see section 2.12

NOTE 1

If the DI-5C is not used for a long time, then it´s necessary
to charge the battery at least once a year.

than to CRANKSHAFT MEASURING position (see ow scheme section 5).

2:4 SETTINGS

2:4.1 Set date & time
Date and time are continuously displayed when the instrument is switched on and
controlled by an internal clock. If the battery runs empty it might be necessary to
re-enter actual time and date. Date is written YY-MM-DD (Year, Month, Date).
Time is entered using a 24 hour clock (no AM/PM). The date format can then be
changed into US format (MM-DD-YY) if desired.
2:4.2 Change number of digits
The display is normally set 3 decimal numbers (i.e. 1/1000 mm) on the display = 4
digits. It is possible to select 2 decimal numbers = 3 digits.
2:4.3 Change limit value
Red and Green indicators are located on the instruments front panel to assist
measurement. The measurement limits are normally set +/- 0.500 mm.
Measurements taken within this range will show a steady green LED.
Should it exceed these limits the Red LED will go on. If you want to make a visual
check only, the limits can easily be reduced to acceptable tolerances indicated
with Green and Red.

2:4.4 Change program mode

When selecting STANDARD MODE by OK, the program (menu) will follow the
Flow Scheme on the last page.
If MEASUREMENT ONLY is selected the display will show current date.
By pressing OK the instrument will remain in measurement only mode.
NOTE ! In this mode the panel buttons operate in the following way;
OK = ON/OFF < = RESET > = ZERO SET ^ = BACKLIGHT on/o.
This mode will be retained on re-starting the instrument and can only be switched
back to STANDARD MODE by pressing the > arrow button when the instrument is
started and displays the current date.
Step to CHANGE PROGRAM MODE and change mode.

Prisma DI Ovality Kit

ITEM NO 488-8100

Cylinder liner maintenance.
The Ovality Kit is an accessory to the Prisma DI-5C and Prisma DI-5.
The method is simply giving 5 measuring points at each level of the
liner. To compare the levels you will also see how much the wear of
the liner is in the cylinder top.

Using the Prisma DI Ovality Kit together with Prisma DI-5C and kit
you do have an outstanding funktion to load all your measurements
into the PC software and print out graphs to see the wear and how
it develops over time.
