Logging mode
While the [LOG] sign is on, measurements will be saved in the internal memory if the [Memory] key is pressed
under a condition where an optional log is being displayed on the screen. A log name must consist of maximum
eight alphanumeric characters. The maximum number of logs is 10. The measurement period depends on the
remaining capacity of the internal memory. The measurement interval should be greater than 1 second and less
than 24 hours.
Capacity of the internal memory
5000 pieces of data with the collector function solely. If using only the logging function, the maximum data
capacity is 20000 pieces.
However, the measured data collected either with the collector function or with the logging function can co-exist
in the internal memory.
Display
Semi-transmission type liquid crystal display (LCD)
8 characters x 2 lines dot matrix display section and icon display section
Display light
Two backlight LEDs for the display section. 10 seconds of duration from the moment when any key is operated
(factory setting: OFF).
Clock function
Controls the date (internal data) and time (internal data and display). The accuracy is within 1 minute per month.
Alarm function
This function can be set to the upper-limit temperature and lower-limit temperature. In both cases, it can be set so
either the alarm is turned on if the temperature falls within or outside the specified range.
Calculation function
Can obtain the maximum temperature (MAX), minimum temperature (MIN), and average (AVE).
Key operation sound function
Possible to set on or off of the buzzer sound when the keys are operated (factory setting: ON).
Auto Power Off function
Selectable from 5, 10, 20, and 30 minutes or infinite (factory setting: 10 minutes).
Low battery voltage alarm
A battery symbol turns on if the set LR6 alkaline dry cell almost expires.
Auto Operation Stop at a low battery voltage
When the set LR6 alkaline dry cell is almost used up, the system power will be automatically turned off after the
“BatteryEmpty” message appears.
Do not leave the used battery being set in the main unit. This may cause operation errors or battery liquid leakage.
Back-up function
Used to back up the measurement data or clock function when the regular LR6 alkaline dry cell is not installed.
The back-up battery has a capacity to retain data for typically six years under the room temperature (23
±
5
C).
Key lock and FUNC lock
Disables the operation keys and function keys other than the Power key (factory setting: OFF).
Specification of the number of display digits
The user can specify whether the least significant digit of temperature display is the first decimal position (i.e.
0.1
C (0.1
F)) or first integer (i.e. 1
C (1
F)). (factory setting: 0.1
C (0.1
F))
