Battery charging
1. The SM11 is equipped with 10 x 1.2V Ni-MH cells giving a total power of 12V 1200mAh. With fully charged
batteries, the energy should be sufficient for at least 200 (max. 400) cycles. Please note that the battery
power will fall slowly even when unit is not used.
2. When the battery voltage is low, the "Low Bat" LED is lit. The LED also makes a short duration flash when
the flag is triggered; this is normal and not a reason for re-charging.
3. Before charging, the unit must first be disconnected from Smart Logger and switched off.
4. Only the battery charger provided (SM12 or SM14) should be used. Use of any other charger may cause
damage to SM11 and batteries.
5. Charge for a minimum of 3 hours.
6. If the unit is frequently used it is recommended that the rechargeable batteries are replaced by the original
equipment supplier or by its authorized representatives or test laboratories at least every 12 months.
Important
In order to optimize battery life the SM11 should be switched off when not in use. In order to ensure optimized
performance batteries must be fully charged prior to stopping measurements be taken.
The SM11 stop flag unit is specifically designed to be used in conjunction with Smart Logger. Interfacing of this unit
to other equipment may result in inaccurate timing and/or equipment malfunction.
Options
When delivered, the SM11 unit is factory set so that the start signal is sent when the flag has moved approx. 10°.
The unit can be set to give a start signal when the flag has rotated approx. 80°. To set the unit to the required
condition the internal jumpers JP3 and JP4 should be connected as follows:
Start signal generated at
10°
80°
The flag rotation of SM11 can be set to automatically reset after approximately 1500ms. This function is intended to
help spare the batteries of SM11. This reset function is optional and can be changed by setting the internal jumper
JP2 as shown in the table below:
