Each momentary press of the REC button will alternately start 
and stop recording. To clear the memory, power off the meter, 
press and hold the REC button followed by the    button, 
holding both on simultaneously for at least 2 seconds. Then 
release both buttons. The display will show "CLR" (as shown to 
the right) indicating that the memory has been cleared. 

Press the MAX MIN button to enter the MAX/MIN mode. In this mode, both the maximum 
and minimum values are simultaneously retained in memory and updated with every new 
data sample. The instrument first enters the MAX mode, and the MAX symbol and value 
are both displayed. Pressing MAX MIN again advances the display to the MIN symbol 
and value. The next press of the MAX MIN button will cause both the MAX and MIN 
symbols to flash. This indicates that the maximum and minimum values have been 
updated in memory and the displayed reading is the present value. Each successive 
press of the MAX MIN button circulates the display mode among these options. To exit 
the MAX/MIN mode, press and hold the MAX MIN button for two seconds. 
In the MAX/MIN mode, the °C/°F  button is disabled, as indicated by two consecutive 
beeps if pressed. 

By default, the instrument powers on in the ‘Auto Power Off’ mode and will automatically 
shut off 30 minutes after the last key operation or RS232 communication.       
To disable this feature, press and hold the HOLD button and then power on the meter.   
Two successive beeps will indicate that ‘Auto Power Off’ is disabled, and the        will not 
be displayed. 

When the battery voltage is at or below the minimum for proper operation, the   
 

symbol will show on the LCD indicating that the battery must be replaced. 

The Digital Output is a 9600 bps N 81 serial interface. 
RX is a 5V normally high input port.
