8.0 OPERATIONAL (TRIGGER) MODES
8.1 Introduction
The Wahl DHS520/520B thermometer has three operating modes:
•
Classic
•
History
•
Burst
The thermometer trigger is used to control
the operation of the thermometer in each
mode. The trigger has two stages: T1 and
T2 (See inset).
A light press on the trigger will move it to
position T1, at which point a stronger press
will be required to move the trigger a small,
further distance to the second position T2.
This section of the user guide describes
the measurement and data collection
options available by using the two-stage
trigger functions.
8.2 Classic Mode
Classic Mode is the simplest operating mode and the one that most closely
resembles the operation of earlier Wahl portable thermometers.
In Classic Mode, the trigger operation is single stage (T1) only. However, note
that in Classic Mode, moving the trigger to the T2 position has no further effect.
All four measured temperature types (Peak, Continuous, Average and Valley)
are displayed on the side LCD panel, although only the highlighted temperature
type is displayed in the viewfinder and
LOG datalogging software (wired connection or via Bluetooth).
