TROUBLESHOOTING AND MAINTENANCE
Warning:
There are no user-serviceable parts in this
instrument. Do not remove cover, as high volt-
ages exist inside the unit. Refer servicing to
your dealer.
Warning:
If thermocouples are at a high voltage, this
voltage will be present at other points inside
the unit.
TROUBLESHOOTING
If the heater output does not function correctly, check the fuse located on the
rear of the unit left of the heater output receptacle. The fuse is rated at 15 A.
Replace it with a fuse having identical voltage and current ratings.
Caution:
For continued fire protection, replace fuse only
with a fuse of the specified current, voltage,
and type. Remove power cord from wall socket
before checking or replacing a fuse. High volt-
ages exist on fuse terminals.
If the unit does not have power, check the fuse located below the ON/OFF
switch. The fuse is rated at 0.6 A for 115 V applications and 0.3 A for 230 V
applications. Replace this fuse with a fuse having identical voltage and cur-
rent ratings.
CALIBRATION
System calibration is described in the setup portion of this manual. Instru-
ment calibration is completed at the factory. No user calibration is required to
meet stated specifications.
MAINTENANCE/CLEANING
Maintenance is limited to fuse replacement. All materials withstand standard
cleaning solvents.
