CAUTION
• If you conduct an open-close check for the contact output 2, Error 1 (cell voltage
failure) or Error 2 (heater temperature abnormal) will occur. This is because the built-
in heater power of the detector, which is connected to contact output 2, is turned off
during the above check. So, if the above error occurs, reset the equipment or turn the
power off and then back on to restart (refer to Section 10.4, “Resetting” later in this
manual).
