7.9 REASONABLE LIMITS FUNCTION
Reasonable limits can be set between 0% and 99% of the range between the high and low limits, and apply
above the high limit and below the low limit.
For example, if the low limit is 100 µm and the high limit is 150 µm, the range is (150 - 100) = 50 µm.
Therefore if the reasonable limits are 20%, then the value applied is (50 x 0.2) = 10 µm.
Therefore, readings outside the range (100 µm - 10 µm) or (150 µm + 10 µm) will cause the reading to flash
and the unit to hold until the reading is either accepted by pressing [ENTER], or rejected by pressing [DEL].
If reasonable limits are set to 0%, every reading outside the high and low limits will require user action. If
reasonable limits are set to 99%, the reasonable limit function is switched off. A different value can beapplied to each limit.
To set reasonable limits, press [SETUP] and use [<] or [>] to select:

The display will show ‘Hi’
Press [ENTER] and use [<] or [>] to adjust the value up or down.

8 STATISTICS
These modes operate within batches and can be selected from the setup menu - see “Datacollection/Statistical functions” on page 24. There are 3 modes available:
8.1 STATISTICS MODE
The stats keys [ ], [σ], [<] and [>] will display (for 1 second or for as long as the key is pressed) mean,
standard deviation, lowest and highest readings whether in immediate or batch (statistics) mode.
In averaging or counted average mode, the keys have different functions at different times within thefunction. These two modes are only available within a batch. Default settings may be setup in immediate
mode. These may be modified for a specific batch by adjusting the settings before taking any readings after
selecting the batch.
8.2 AVERAGE MODE
Average mode allows the user to take a number of readings to obtain an average value (viewed using the[ ] key), and store it as a reading in the batch. Individual readings are displayed as taken. The averagevalue may be stored by a single press of the [ENTER] key. At this point, the display will show the averagevalue being stored (with the [ ] symbol) and how many averages have been stored. Whilst taking an
individual reading, the readings display will show how many readings have been taken so far and the [ ]symbol flashes to show that the instrument is in averaging mode.
The statistics keys will show the statistics for the individual reading until the [ENTER] key is pressed. Whenpressed, they will show the batch statistics.

26

R

8.3 COUNTED AVERAGE MODE
The user predetermines how many readings should be taken to produce the average. This number is set
within the SEL mode of Setup.
As readings are taken, the reading number display shows ‘n’ and the number of readings taken so far. The[ ] symbol indicates that the main display is a true average. When the pre-determined count is reached,a double beep will sound (the second beep will be extended and the red LED will show if the stored reading
is out of limits). At this point, the reading number displays the number of averages stored, and the main
display shows the last average saved. The statistics keys will show the batch statistics at all times in this
mode.

12 STORAGE
This gauge incorporates a Liquid Crystal Display (LCD). If the display is heated above 50°C
(120°F) it may be damaged. This can happen if the gauge is left in a car parked in strong sunlight.
Always store the gauge in its carrying pouch when it is not being used.
Remove the batteries from the gauge and store them separately if the gauge is to remain unused
for a long period of time. This will prevent damage to the gauge in the event of malfunction of the batteries.

13 MAINTENANCE
You own one of the finest hand-held coating thickness gauges in the world. If looked after, it will last alifetime.
If you are not sure if your gauge is performing correctly, please contact Elcometer or your local Elcometer
supplier for advice.
If during calibration thesymbol appears, this indicates that servicing is required.

If thesymbol is flashing, the instrument can still be used, but it should be returned for service at thenext convenient opportunity.
If the symbol remains solid on the display while the instrument is switched on, then the instrument cannot
be calibrated and should be returned for servicing immediately.
If you return your Elcometer 355 for any reason, please describe why as fully as possible. Make sure thatyou include any probe modules that are associated with the condition, as most faults are associated withthe consumable item (the probe) and an alternative module may allow further use of your gauge. Regularchecks of the probe module performance are therefore recommended.
35

substrates, consisting of a zero plate and 4 thickness values to Customer’s requirements and measured toan accuracy of 1% or 1mm whichever is the greater. These Standards are all supplied with a Calibration
Certificate.
14.3 Precision hand grip

The Elcometer 355 is supplied with a precision hand grip for use with the F1, F2 and N1 standard styleprobes. The grip is designed to help control the placement of the probe on surfaces in a repeatable way sothat the optimum accuracy capability can be achieved. The grip controls the cable and positions the tip at
39

Rright angles to the substrate to avoid any errors that are introduced by variations in these parameters. The
probe can be used without the grip where the smaller diameter probe is advantageous, but some effect on
accuracy may result from the probe twisting between measurements or not being truly set at right angles tothe substrate. If a replacement Hand Grip is required, use Sales Part Number T35512026.
14.4 Probe placement jig

A probe stand which can be used to position a range of probes on small components is available. Use Sales
Part Number T95012880.
14.5 Protective covers

The Elcometer 355 is supplied with some clear plastic, disposable sheets which protect the unit fromoverspray. Additional covers are available in lots of 10. Use Sales Part Number T35512051.
14.6 Re-chargeable batteries

The Elcometer 355 can be operated using 3 x 1.2 V nickel metal hydride (NiMH) cells which are charged
externally. Suitable chargers are available for all voltage options.
14.7 Dry batteries

The Elcometer 355 can be powered by 3 x 1.5 V (LR6) AA alkaline cells. Zinc carbon batteries will give ashorter operating life.
14.8 Headphones/earpiece

The Elcometer 355 has a 3.5mm jack socket fitted to the top end plate next to the 25 way D socket. Thismay be used with an earpiece with volume control (Part No. T35512220) or with headphones (Part No.
T35512216) so that the beeper signals can be heard in high ambient noise environments.
