4. DESCRIPTION OF TEST PROCEDURE
4.1 General
Rotor or sha vibraons are usually measured by means of non-contact eddy-current displacement
probes. You measure the relave moon between rotor and the installed probe. With the Dynamic
Signal Checker the funconality of such systems can be tested on the basis of realisc simulaons of
vibraons.
The Dynamic Signal Checker consists of a compact housing which contains an electrically driven
vibrator. Aer the probe to be tested is clamped in the prism holder, use the GAP adjustment ring
to obtain the necessary voltage (typically 8 to 10 VDC). In combinaon with the compact, baery
driven, handheld control unit the checker can be set into dened oscillaons with 112 Hz and dierent
amplitudes.
With this, the Dynamic Signal Checker enables a funcon test of the enre loop (that is the probe,
driver/transmier funcon, wiring, indicaons and alarms) in one step.
The baery-powered handheld control unit can be aached comfortably by means of the magnet on the
back of the device. The rechargeable baeries enable operaon up to several hours.

4.2 Vibraon Amplitudes
Aer having determined the loop sensivity (probe, cable, driver/transmier) by means of a suitable
stac calibraon unit (e.g. the 9060-001) and a calibrated voltmeter, the Dynamic Signal Checker
vibraon amplitudes can be simulated precisely. The accuracy of the simulaon goes hand-in-hand with
the accuracy of the used voltmeter. With this, the complete system (probe, driver/transmier funcon,
wiring, indicaons, alarms) gets tested.
Basic descripon of the measuring principle:
The Dynamic Signal Checker creates a clean sinusoidal signal with constant frequency (112 Hz) and
variable amplitude, which is picked up by the proximity probe. At the buered-out of the driver/
transmier or monitor this vibraon can be measured as RMS value by means of a common voltmeter
set to “AC”.
This RMS value can be converted accurately into a peak to peak value, using following formula:
Example:
Reading buered-out: 0.2263 VAC = 226.3 mV AC
Typical sensivity: 7.87 mV/µm (200mV/mil)
Vibraon amplitude [µpp]: 226.3 * 2 * 1.414 / 7.87 = 81.3µm pp,
226.3 * 2 * 1.454/200 = 3.2 mils pp
Simplied formula for the typical measuring loop sensivity of 7.87 mV/µm (200mV/mil):
Spp [µm] = 0.359 * RMS [mV]
Spp [mils] = 0.0141 * RMS [mV]

Valid for 7.87 mV/µm (200 mV/mil)

4.4 Test Procedure
1. Before the dynamic test with the Dynamic Signal Checker the measuring loop sensivity has to be
determined, since deviaons from the specied sensivity inuence the accuracy and indicaon. Using
a stac calibrang unit like the METRIX 9600-001 and a calibrated voltmeter you can verify that probe,
cable and driver match the specicaon
(typically: 7.87 V/mm, 200mV/mil).
2. Place the Dynamic Signal Checker on a solid surface.
3. Screw the GAP adjusng ring + lock ring up to about 1 mm into the upper part of the housing.
4. Connect probe including extension cable with driver/transmier.
5. Connect the voltmeter with the driver/transmier. Set the voltmeter on “DC” in order to read out
the GAP voltage.
6. Carefully insert the probe or the probe holder with reverse-mount probe, into the GAP adjustment
ring and clamp it in the prism holder at a gap signal of about 10 VDC. Avoid contact with the vibrator in
order to not damage vibrator or probe p. Fine adjustment can be achieved by turning of the adjusng
ring; then x it with the lock ring.
The prism holder is suitable for probe diameters of 8 … 22 mm.
7. Connect the simulaon unit to the handheld control unit.
8. Aer pressing the ON/OFF (“ ”) buon once, the device performs a self-test (ashing of all 5 LEDs).
As soon as the “ON” status indicator lights up, the device is ready for operaon.
9. By further pressing of the “ ” buon one by one up to 4 stored default amplitude values (see 11.
for adjustment) can be selected. The amplitude can be read from the voltmeter as RMS voltage signal
[mV] and converted to [µm pp, mils pp] via calculaon formula (p. 4), conversion table (p. 5) or diagram
(p. 6).
10. If the vibraon indicated in the control room doesn’t correspond with the mV signal of the
voltmeter, this may be due to one of the following causes:
• The wiring of the measuring loop is not correct or even broken.
• The vibraon driver/transmier is defecve or calibrated with a wrong measuring range.
• The limit monitoring in the PLC downstream of the transmier is calibrated with
a wrong measuring range.
• The input card of the vibraon monitor is defecve or falsely adjusted, thus a wrong value
is transferred to the monitor.
• The measuring range of the vibraon indicaon is falsely adjusted.
11. In order to adjust individual default values (possible within the range of 0 … 250 µm, 0 to 10 mils)
following steps are necessary:
• Connect a calibrated voltmeter to the buered-out of the exisng driver/transmier or
monitor and set it to “VAC”.
• Read the corresponding mV value of the desired vibraon amplitude from the table (p. 4)
or diagram (p. 5).
• Adjust the vibraon amplitude according to the mV value by means of pushing the buons
“ ” resp. “ ”. You can choose between holding the buons (fast change of values) or
just tapping the buons (slow change of values for rather sensive adjustment).
• The adjusted value is to be compared with the operaon indicaons.
4.4 Test Procedure
• In order to save the individually adjusted value, as shortcut level for future adjustments,
select one of the 4 storage posions (green LEDs) with the buon “ ”. By pressing of
the buon “S” the stored value will be replaced by the new selected value. Note
that, depending on the baery status (14.) and the posion (2.) of the Dynamic
Signal Checker the actual amplitude corresponding to the stored values may slightly dier
over me. The correct seng can be updated anyme.
12. In order to switch the device o manually, the ON/OFF (“ ”) buon has to be pressed for > 2
seconds. If no operaon is performed over a period > 30 minutes, the device switches o automacally.
13. If the “ON” indicator blinks, the device has to be charged. Before damaging exhausve discharge
starts, the device is automacally switched o; 5 seconds ahead all LEDs start blinking.
14. In case of low baery the device can be powered using the USB charging cable.

5. RECHARGEABLE BATTERY
In order to charge the device, connect the charging socket with the provided USB power adapter. As
soon as the baery has reached its full capacity, the charge indicator lamp goes o. The baery should
always be charged when storing the device for longer periods of me.
SAFETY INSTRUCTIONS FOR LITHIUM ION POLYMER BATTERIES (LiPoly baeries)
LiPoly baeries are rechargeable accumulators that feature an extremely high level of energy density.
This type of baery has to be handled with parcular care when in use and when charging/discharging.
Mishandling can lead to a premature wear out or defect, or permanent damage.
Self-Discharge:
LiPoly cells have an extremely low self-discharge rate (approx. 0.2% per day), which is why they can be
stored over longer periods of me without any problems. If the voltage drops below 2.5 volt/cell, it is
imperave that the cell is recharged.
An exhausve discharge is to be avoided, otherwise the cell can suer permanent damage in the form
of capacity loss.
Durability:
The theorecal durability or lifespan of a cell with low levels of discharge currents lies at around approx.
500 charging/discharging cycles. A used baery has to be disposed of correctly!
Baery Disposal:
Never throw used baeries in the regular garbage. In order to help protect the environment, defecve
and used baeries have to be handed in at the appropriate collecon points and in a discharged
condion. Collecon points can be found at the sales outlets for baeries or at municipal collecon
points for hazardous waste. Please mask the bare contacts with adhesive tape in order to avoid short
circuing.

DISCLAIMER
Due to the fact that Metrix cannot monitor the handling of the baeries, any liability and warranty is
expressly disclaimed with regard to incorrect charging / discharging or handling.
