CHAPTER 2 Checks and Preparation
Regarding Maximum Input Voltage
To avoid break-downs or short-circuiting accidents, please make sure to abide by the items written below.
In case the input voltage exceeds the specifications, the circuit at the input part will break down. Please don't
input it.
< Between input terminal (+)/input terminal (-) >
• Maximum input voltage : DC60Vp-p
< Between input terminal (-)/input terminal (-) >

Notes on temperature
When measuring the temperature, please pay attention to the following.
•
Do not block the air vents of the GL840. Leave a clear space of at least 20 cm around it.
•
When rapid temperature change occurs in the input terminals, the error may occur on the measurement.

: 60Vp-p
: DC60Vp-p
: 350Vp-p/1 minute
