Powering-up the Orbis
Fitting and charging of rechargeable batteries
AC operation
Fitting of alkaline batteries
The Orbis is supplied with a set of 5 Nickel Metal Hydride AAA rechargeable batteries. For safety reasons during transportation the batteries are shipped discharged. To obtain maximum battery life we recommend that you charge them with the charger/adaptor supplied for at least 14 - 16 hours when you first receive the Orbis.
To insert the batteries you must first remove the battery cover on the underside of the unit by undoing the 4 retaining screws. Fit the 5 batteries in the battery holder ensuring that you observe polarity and the batteries are placed on top of the ‘release tag’.
To remove the batteries simply pull the ‘release tag’ and they will be freed from the spring-loaded contacts.
Refit the battery cover and tighten the 4 retaining screws.
Connect the AC adaptor/charger to the Orbis charger socket on the rear of the case and charge the batteries for 14 - 16 hours. Only use the adaptor/charger supplied.
The Orbis can also be powered directly from an AC power supply. This can be achieved with or without the rechargeable batteries being fitted. Connect the AC adaptor/charger to your AC supply. Only use the adaptor/charger supplied.
If rechargeable batteries are fitted, a trickle charge will be applied to the batteries.
The Orbis can also be powered by AAA 1.5V alkaline batteries (not supplied). For the fitting of alkaline batteries, follow fitting instructions as per rechargeable batteries above.
Warning:
When alkaline batteries are fitted, the AC adaptor/charger must NEVER be connected to the Orbis due to risk of leakage which could damage the instrument.

The Orbis is supplied with 4 pegs which grip the sample during testing.
Screw the pegs into the runners on the top fixture equally spaced to ensure the sample is securely gripped when the runners are brought together using the star handle on the end of the lead screws.
Ensure that the pillars are finger tight and the sample securely clamped otherwise rotation in the fixture will occur during testing.
As shown in Figure 1 the control panel has 6 keys:-
To power up the Orbis press the red key. A short self-test runs during which the display will show the capacity in ‘N.m’ (newton meters).
After the self-test, providing no torque has been applied to the instrument, the display will show all zeros. This is because the Orbis re-zeros itself during the self-test routine.
If a torque is applied rotationally via the fixture, the reading on the display will register the applied torque.

* Do not overload the transducer, as this could cause
irreparable damage.
Loads greater than 120% of full-scale will produce an audible beep until load is released and an OL symbol will appear on the display
for 30 seconds
.
Loads greater than 150% of full-scale will produce an audible beep until load is released and an OL symbol will appear
permanently
on the display. Consult your supplier to arrange
repair.
To power down the Orbis press the red key.
Clockwise torque is displayed on the Orbis and recognized by the symbol shown in Fig. 2.
Counter-clockwise torque is displayed on the Orbis and recognized by the symbol shown in Fig. 3c.
A torque indicator bar alerts the operator to how much load has been applied to the transducer. As the load approaches the maximum rating of the transducer, the indicator bar changes appearance when above approximately 80% of the rated capacity. This warns the operator that steps should be taken to prevent excessive torque being applied.

For counter-clockwise torque the indicator bar is solid then dotted. For clockwise torque the indicator bar is dotted then solid – see fig. 3b & 3c
During the operation of the Orbis it is sometimes necessary to zero the display – e.g. when you wish to tare out a displayed torque applied by the sample, so it does not become part of the measured reading. Press and release the ZERO key. The display will blink momentarily as the zero operation is carried out.
You can choose from the following units of measurement depending on the capacity of your Orbis: N.m, N.cm, mN.m, gf.cm, kgf.cm, kgf.m, lbf.ft, lbf.in, ozf.in.
To change the display units press and release the UNITS key. Each successive key press will select the next available units until the Orbis returns to its original setting. The Orbis automatically converts readings as new units of measurement are selected.
The Orbis detects and stores maximum (peak) torque in both clockwise and counter-clockwise directions.
Press the MAX key. The display will show the word MAX together with the highest counter-clockwise torque and the highest clockwise torque detected during the test. The current load being applied to the transducer is also displayed.-
see fig 3a overleaf

Press the MAX key again and the word MAX has now disappeared from the display. The display will now indicate torques applied in both directions as they are applied to the transducer and maintain a "running" display.
Press the RESET key to clear both maximum registers and prepare for detecting the next maximum readings.
The Orbis has RS232, Mitutoyo and analogue output signals. It is possible to transmit the displayed reading to peripheral devices (e.g. PC, printer) by pressing and releasing the TXD key.
Displayed readings can also be requested individually from a PC via the RS232 interface by sending a"?" (ascii D63 [3fh] ) character. When using the Orbis for creating a graphical presentation of data, ensure that the normal mode is selected, not max modes.
For sending a continuous data stream to a PC, press and hold the TXD key for 2 seconds then release. TX will now appear in the display to indicate that information is being sent. To stop sending data, simply press and release the TXD key, at which point TX will disappear from the display.
Please note that the continuous data stream only starts when approximately 2% of the rated capacity of the Orbis is reached.
To differentiate between clockwise and counter-clockwise measurements when transmitted to peripheral devices counter­clockwise results are prefixed with a minus sign. If required the minus sign can be removed in the sign suppression menu accessed by pressing both RESET and UNITS while turning the instrument on. Press TXD to select option required and RESET to confirm selection. Press MAX to return to the testing screen.

It is possible to activate a back-light on the Orbis display. Press and hold RESET whilst powering-up the Orbis with the
key. The back-light is now operating.
Please note that battery consumption is doubled when using the back-light.
To conserve battery power, it is possible to activate an Auto­off function so that the Orbis powers down after 2 minutes since the last key press.
Press and hold ZERO whilst powering-up the Orbis with the
key. The symbol ‘Ao’ will appear in the display to
indicate Auto-off is active.
It may be desirable to reverse the display, so that it can be easily read with the handle positioned on the right-hand side. By pressing and holding MAX whilst powering-up the Orbis with the key, the display is inverted.
If you suspect that your transducer has sustained an overload it is possible to check the status of the torque sensor immediately.
Symptoms of overload may be (a) OL in display (b) buzzer sound (c) torque indicator bar present even under zero load.
Place the Orbis horizontally on a flat level surface. Press and hold UNITS until the password menu appears with 0000 in the display. Press RESET four times and you will now see a value shown as %.

The Orbis TE Tamper-Evident Torque Tester
The Orbis TE provides all the features and benefits of the basic Orbis for measuring the application and removal torque of standard screw closures together with a unique selectable facility (see Optional settings, Turning on and using the TE Option) for measuring tamper­evident seals.
When testing tamper-evident caps and seals with the Orbis TE the software within the unit enables the value at both the ‘slip torque’ (1
st
peak) and ‘bridge torque’ (2ndpeak) to be measured and displayed. Once calculated either result or both can be transmitted to a peripheral device (see Optional settings, Data selection menu).
Different designs for tamper-evident seals can produce slightly different profiles when tested. To accommodate this the Orbis TE has an adjustable feature (% drop) to ensure the correct values are calculated on different types of seal.
The % drop feature is based on the capacity of the Orbis unit which is 1.5, 6, 10N.m and refers to the amount that the 1
st
peak
to be calculated must drop before the software starts to look for the 2
nd
peak. The default setting is based on a % drop of 5. This can be adjusted depending on the profile of the cap to be tested (see Optional Settings, Setting the % drop).

Introduction
If possible complete the test by applying torque smoothly in a single turn. This will ensure that accurate peaks for both slip torque (1
st
peak) and bridge torque (2
nd
peak) are calculated.
When setting up the Orbis TE a graphical representation of the test provides a clear insight into the % drop factor required. Please contact Mecmesin Corporation or your approved supplier for details on DataPlot graphical charting software.
