• Do not use a pointed object (such as a pen) to press the keypad buttons. Wrap the
Smart Timer separately when transporting it with other items. The transparent
covering over the keypad can be creased by a fingernail or other sharp object.
• Clean the keypad with a soft cloth and mild detergent, avoiding hard rubbing of the
transparent window.
• Do not leave the Smart Timer exposed to direct sunlight except for brief periods.
Strong ultraviolet light can damage the Smart Timer display.
• Remove the batteries prior to storage for more than one month. Batteries can leak
and damage the internal circuitry, especially if the batteries are old.
• For best results, use alkaline batteries. Rechargeable NiCad batteries may be used,
but the operating time between charges is much shorter than the lifetime of alkaline
batteries.

Resolution:
The basic timing resolution of the Smart Timer is 100 microseconds in all
modes except Stopwatch, which is 10 ms.
Calculated Values:
Calculated values are displayed to one or two decimal places with
typical accuracy being +/- 1 in the least significant digit. For extremely high speeds (such
as might be generated by hand spinning a Super Pulley), accuracy is degraded for
calculated parameters because of the very short timing intervals involved.
Maximum Output Power:
The Smart Timer allows many different accessories to be
used as inputs. The total 5-volt load (both inputs added together) that can be
accommodated is 180 mA, maximum.

The following PASCO accessories are available to help extend the utility of the Smart
Timer. See the current PASCO catalog for more information.
Accessory Photogate (ME-9204B):
The stereo phone plug of the Accessory Photogate
plugs into either of the phone jacks on the side of the Smart Timer, giving you the option
of two identical photogates operating from a single timer. (Some of the experiments in
this manual require the use of a Smart Timer with two Accessory Photogates.)
