Operating Instructions
For overseas shipment, analyzers are shipped with the 15-Pin D
connector DISCONNECTED from the circuit board. This is to
preserve the battery life during shipment. To re-connect the wire
bundle, simply open the analyzer by removing the 2 screws
located on the right side panel. They are located about 1 inch from
the top and 1 inch from the bottom, on the door. (fig. 2 pg. 6) Re-
connect the 15-pin D connector and allow 24 hour stabilization
prior to use.
2.0 Setting the Alarm
Normally, the alarm is set at the Factory at 50% of full scale. The
alarm can be reset to any desired level by following the procedure
below. Minimum alarm level must be greater than 5% of the full
scale measuring range.
Set FUNCTION switch to ZERO. Using the ZERO control,
advance the LCD display to the desired alarm set point. Some
analyzers require the use of span tool (provided). Adjust the
ALARM SET (fig. 1 pg. 4) control until the alarm sounds. Adjust
the ZERO control slightly counterclockwise until the alarm is silent.
To confirm setting slowly adjust the ZERO control clockwise until
the alarm sounds. Re-adjust the ALARM SET control if
necessary. Adjust the ZERO control for a reading of “0” on the
display.
