Nickel-cadmium cells will self-discharge when the instrument
is not used or is stored for extended periods of ti me. The
rate of self-discharge is dependent upon temperature and hu
midity. When the instrument is to be stored for extended
periods of time, particularly at high temperature or high hu
midity, the batteries should be charged for at least 16 hours
every two weeks, or leave the 213 connected to the power
line.
POWER LINE OPERATION
This instrument can be operated from a power line voltage
of 90 to 136 V, 48 to 62 Hz (180 to 250 V, 48 to 62 Hz or
180 to 250 V de for Option 1).
OPERATING TEMPERATURE
The 213 can be battery operated in ambient air temperatures
between -15 and +55
°
C (+5 and +131
°
F). It should be con
nected to the power line only in ambient air temperatures
between O and +40
°
C (+32 and +104
°
F).
POWER LINE FUSE REPLACEMENT
To replace the power line fuse requires removal of the top
and bottom cabinet halves (removal of top half necessitates
removal of the bottom half for reassembly of the power cord
and probe leads). Proceed as follows:
WARNING
I
Potentially dangerous voltages exist inside this
instrument when it is operating. Disconnect the
instrument from the power line and turn it off
(disconnecting the instrument from the power
line does not turn it off) before removing the
cabinet halves.
1. Unwind the probe lead and then the power cord. Turn
the instrument on its top and remove the four screws hold
ing the cabinet together (see Fig. 7). Two of the screws
are located inside the probe storage slot.
�
The instrument is not secured to either cabinet
half except by a tight fit around the crt face
plate; therefore, if the instrument remains at
tached to either cabinet half as it is lifted off, it
can drop free and be damaged.
2. Remove the bottom cabinet half and note the position
of the power cord and probe lead inside the rear of the ca
binet.
3. Lift the instrument out of the top cabinet half.
