Once the temperature reaches 2 100 F for example the logger will switch to the faster logging rate and record data every 10 seconds until the temperature falls back below the high limit or 2 000 F in this case At that time logging then resumes every 5 minutes at the normal logging interval Similarly if the temperature falls to 250 F for example then the logger would switch to burst logging mode again and record data every 10 seconds Once the temperature rises back to 200 F the logger will then return to normal mode logging every 5 minutes To set up burst logging 1 Select Burst for Logging Mode in the Launch Logger window If Burst has already been configured for this logger click the Edit button in the Launch Logger window Note that you cannot set up alarms with burst logging You also cannot select the Stop Logging option Never wrap when full if burst logging is configured 2 Inthe Burst Logging window select the High Limit checkbox if you want to set up a condition in which burst logging will occur when the sensor reading rises above the high limit value Type in the value or drag the red upper slider 3 Select the Low Limit checkbox if you want to set up a condition in which burst logging will occur when the sensor reading falls below the low limit value Type in the value or drag the blue lower slider i mm A t x y Burst Logging oS While any of these condition s are met Sensor 3 Thermocoupl
