Trigger Lock (66/68)

To lock the unit on for continuous measurement, slide the bottom
switch down. See Figure 2. If the trigger is pulled while the unit is
locked on, the laser and backlight will turn on if they have been
activated. When the unit is locked on, the laser will turn off when
the trigger is released. However, the backlight remains on unless it
is turned off using the keypad.

To turn the backlight and laser on or off, slide the backlight and
laser switch to the appropriate position. See Figure 2.

Function Button Functions (66/68)

Models 66 and 68 measure Maximum (MAX), Minimum (MIN),
Differential (DIF), and Average (AVG) temperatures each time a
reading is taken. DIF shows the difference between maximum and
minimum temperatures measured. AVG shows the average
temperature reading for each time the trigger is pulled or the unit is
locked on. This data is stored and can be recalled with until a
new measurement is taken. See "Hold" for information on how to
recall stored data. When the trigger is pulled again, the unit will
being measuring in the last mode selected.
Pressing also allows access to the High Alarm (HAL), Low
Alarm (LAL), Emissivity (EMS), Probe temperature (PRB-only
available when the probe is connected to the thermometer), and
Data logger (LOG). Each time is pressed the unit advances the
function cycle. Figure 7 shows the sequence of functions in the
function cycle.
