Instrument Function Menu
The instrument menu is accessible from the keypad and offers the following user defined settings:
Data Input -will allow specific sample number and location information to be attached to a sample record. Each sample captures a unique ID number, date, time and reading in addition to the 2 user definable parameters.
Set Sensitivity -the instrument has 3 sensitivity settings accommodating a wide range of Tryptophan concentrations. Concentrations can be measured from 0.025ppm to 25.0ppm Tryptophan.
Backlight -may be set to desired intensity as light conditions require and will automatically be turned off after 5 minutes of inactivity to preserve battery life.
Auto Sampling -using a flow cell and pump the instrument may be set up to carry out a series of measurements over a specified period at user defined intervals. The results may be written to either the internal memory or to an external data logger.
The internal memory is capable of storing approximately the following:
1.3 days sampling at 1min intervals
20 days sampling at 15min intervals
83 days sampling at 1hr intervals
250 days sampling at 3hr intervals

The SMF4 is powered by NiMH rechargeable batteries, which give a useful operating period of approx 30hrs with the backlight on. When logging in sleep mode at hourly intervals the battery life is approximately 4 weeks. Approx 8hrs full recharge time required using provided charger.
Battery life is shown by a battery level indicator icon on the LCD display.
