The Keypad
When turned on, MICROSCANNER will flash the
LCD power-up test and then resume the test
mode that was last executed. MICROSCANNER
will turn off automatically when no cable is
detected and no key has been used for 10
minutes.
Press ꢀꢀꢀ to quickly change pairs or adjust
values. The ꢀꢀꢀ keys are only active if the
indicators are shown on the display
Operating Mode
Press MODE to select the desired test. The
available modes are: WIREMAP - OꢀꢀICE

Calibration Mode
+
Turn the MICROSCANNER Oꢀꢀ, then hold the
MODE key down while pressing the ON key to
start 'Calibrate' mode. Use MICROSCANNER to
calibrate cable lengths of more than 50 feet (15
meters) and up to 1500 feet (457 meters.)

Setting the NVP percentage
Once in Calibrate Mode, the default NVP
(Nominal Velocity of Propagation) will be
displayed followed by the overall cable length. The
cable length is measured with the currently stored
NVP.
NVP is the measure of how fast a signal travels
down a cable compared to the speed of light. The
result will be represented as a percentage of the
speed of light. %or an accurate length test, the
NVP must be set correctly.
If you know a cable's NVP, change the displayed
numbers using the ꢀꢀ keys until the appropriate
NVP is displayed. The cable length will automati-
cally adjust to the new NVP.
If you know a cable's length, change the shown
NVP using the ꢀꢀ keys until the appropriate
length is displayed. The NVP can be adjusted in
1% increments, and the length changes accord-
ingly.
Cables used for calibration must be at least 50
feet (15 meters) long. Cable lengths of less than
50 feet will display ꢀAULT.

Changing Display from Meters to ꢀeet
During Calibration you will be able to switch the
displayed length from meters to feet by simply
pressing the MODE key.
Press the ON/Oꢀꢀ key once the desired cable
length or NVP is displayed to terminate 'Calibrate'
mode and store the new calibration factor.
MICROSCANNER will use it for future length
measurements until another calibration is
performed.
Battery
MICROSCANNER requires a 9 Volt Alkaline
battery. The Battery icon is displayed on the
screen when MICROSCANNER detects a low
battery condition.
Using MICROSCANNER with a low battery may
effect the test accuracy.
If MICROSCANNER is stored for more than one
month, the battery should be removed.
Note: MICROSCANNER will not function properly
with a 9 Volt Carbon Battery.
High Voltage Protection
MICROSCANNER is designed to withstand input
voltage conditions that arise from normal
telephony applications such as 48 VDC at less
than 80 ma or 24 VAC used to power many
keysets. Tests cannot be performed when hazard
conditions exist on the inputs.

MICROSCANNER Tests
Wiremap
The Wiremap function tests twisted-pair cabling
for proper wiring. Your cabling configuration is
checked for shield continuity, opens, shorts,
crossed pairs, split pairs, and reversed pairs. Test
Results are displayed as a numeric representa-
tion, where the upper line of fixed digits shows the
detected wires at the MICROSCANNER jack, and
the lower line of digits indicates the actual wiring.
This function requires the use of the Wiremap
Adapter at the far end.
1. Connect the cable to be tested to the MAIN
jack (identified on the unit right above the
modular 8 jack).
2. To display the Wiremap screen, press the
MODE key until the word WIREMAP
appears on the screen.
%ollowing are examples where MICROSCANNER
did not detect any faults.

When the wiring fault includes shorted or
swapped non-pair pins (e.g. non-pair pins 1 - 3),
the wiremap will display dashes for those
numerical wire indicators.
Patch Cable Wiremap
The Wiremap function can also be used to verify
patch cables.
1. Simply plug the two ends of a cable into the
two modular 8 jacks (MAIN and LOOP
BACK) on MICROSCANNER.
2. To display the Wiremap screen, press the

Toner
Toner is a cable tracing function that assists in
tracking cables hidden in walls, ceilings, floors, or
patch panels by generating four distinct multi-tone
signals that can be received by a cable tracer. To
trace a cable, use Microtest's Cable Tracer II, or
any equivalent tracing device, to convert a signal
on the cable into an audible tone. To determine
the cable path, simply trace along the wire using
the audible tone as a guide. The tracer needs to
be within one foot of the hidden cable. You may
select one of four different tone sequences,
displayed as the numbers 1-4 on the LCD.
1. To display the Toner screen, press the
MODE key until the words SIGNAL and
TONE are displayed on the screen.
2. To select a different tone sequence press the
ꢀ or ꢀ key.
Display for time frames with #3 signal tone
To enhance the signal insert a grounding plug into
the ground jack located next to the MAIN and
LOOPBACK jacks. A grounding plug is included
in the optional Cable Tracer II kit. You may use
any grounding cable that has a standard insulated
phone tip plug.
