VOL TS-mA/DIV-lnner ring (black scale) indicates
the calibrated voltage or current vertical deflection
factor selected for oscilloscope display when the
VOL TS-mA/D IV VAR control is in the CAL detent.
Outer ring (blue scale) indicates the full scale range
selected for the digital multimeter.
@
PWR (BTRY)-Lights when instrument is on and suf-
ficient battery charge is available. Light extinguishes
when battery requires recharging.
@
n-Selects resistance mode for digital multimeter.
RMS button must be in the out position when mea -
suring resistance or the reading accuracy will be de-
graded.
@
mA-Selects current mode for either digital multime-
ter or oscilloscope function.
@
SEC/DIV-Selects the calibrated sweep rate for the
oscilloscope when the HOR IZ MGF VAR control is
in the CAL detent.

should be stored in the rear panel insulated compart-
ment. To store the power cord, wrap the cord in the
direction of the arrow located on top of the vinyl
cord wrap cover. On the last wrap, store the plug in
the insulated compartment.
PROBE STORAGE
To store the probe, lay the common clip lead parallel to the
probe lead, and attach the common clip to the probe lead
with the small plastic clip provided on the common clip.
Then snugly wrap the leads in the direction of the arrow on
the vinyl cord wrap cover (see Fig. 2-4). When the common
clip is in position to be wrapped into the bottom side of the
storage slot, gently press the common clip down into the
slot (see Fig. 2-4) and continue to wrap the leads. As the
wrap is completed, carefully guide the probe into its place
in the top slot of the vinyl cover (see Fig. 2-3) and gently
press the probe down into the slot.

PROBE CHARACTERISTICS
ON 200-SERIES INSTRUMENTS
I
I
1480- 13
On the 200-series instrument probe(s), each probe body
assembly is designed to meet the input resistance and at-
tenuation factor for the specific instrument type. These
assemblies are not interchangeable between all 200-series
instruments; therefore, when more than one type of in-
strument is being repaired, it is possible for the wrong
probe body assembly to become installed on the probe.
Figure 2-5 shows how to identify the assembly.
To verify that the proper probe body assembly is installed
on the probe, correlate the assembly with the Tektronix
Part Number shown in Figure 2-5. Then compare that part
number with the correct probe body assembly part number
listed in the Mechanical Parts List section.
