Safety guidelines

Caution!
Whenever it is likely that the protection has been impaired, the
device shall be made inoperative and secured against uninten-
ded operation.
The protection is likely to be impaired if, for example:
• the device shows visible damage
• the device fails to perform the intended function
• prolonged storage at temperatures above 70 °C
• severe transport stresses
In this case, a professional routine test must be performed.
This test should be carried out by the manufacturer.
Caution!
Take protective measures against ESD when the sensor socket
is open. At measuring temperatures from -20 to +100 °C the
temperature detector can be automatically identified.
The charging time of the battery may vary when a USB port with
lower power output is used. Temperatures above 50 °C may
result in loss of battery capacity.

Inserting the Batteries

With four AA batteries, the HandyLab has an operating time of over 1000 h.
Open the battery compartment on the rear of the device. Be sure to observe
the correct polarity when inserting the batteries (see markings in the battery
chamber). Close the battery compartment cover and screw it handtight.
A special lithium-ion battery suited to the battery compartment is available
for the HandyLab 750. The battery is recharged through the USB port.
Note: Not available for the HandyLab 750 EX (device variant for applications
in hazardous locations).
