2.0 Operation
2.1 Push
button
The push button is used as a function selection switch. There are 3 basic ways to use this button:
•
SHORT PRESS – Short depression of the button, lasting more than 0.1 seconds but less then 1
second.
•
LONG PRESS – Long depression lasting, lasting more than 1 second but less then 2 seconds.
•
HOLD – Press and hold for more than 5 seconds.
Activation shorter than 0.1 sec is called SPIKE and is ignored by the system. Activation longer than 2
seconds starts the Switch OFF procedure, but if activated for less than 5 seconds it changes to LONG.
2.2 Battery
The unit operates off a single AA battery. The system recognize two types of batteries – rechargeable or
non-rechargeable. Non-rechargeable means alkaline battery and two types of rechargeable batteries can
be used: Nickel-Cadmium (NiCd) or Nickel Metal Hydride (NiMH).
The battery is loaded by removing the battery cover – use a finger-nail or coin in the groove in front of
the slot on the rear to lever the battery door open. Insert the battery in the battery compartment, being
sure to place the bottom of the battery on the spring and the top to the brass terminal. Seat the battery
firmly in place above the removal strap then clip the battery cover in place.
NOTE
: All measured data is stored in non-volatile memory and they remain in the memory even if the
battery is removed after the correct power-down sequence.
CAUTION
: If you remove the battery while the GR-100 is in operation, your data will be lost. Please use
the correct power-down sequence before removing the battery to ensure that data will not be lost.
NOTE
: The time/date information will be lost if the battery is removed for more than one minute.
Therefore, it is recommended to replace battery within one minute to avoid the time and date reset.
First prepare the new battery to be installed. Then remove the old battery and quickly replace it with the
new one. If you experience any problem with the new battery, reinstall the old battery back until the
problem is resolved. The old, nearly discharged battery will not be sufficient for operation of the
equipment, but it will keep the time and date for a while. If the time and date is lost, it can be easily
reset manually upon first power-up, or by the PC when connected.
