MICROSCANNER ENGLISH - 4 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.
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. For an accurate length test, the NVP must be set correctly.
MICROSCANNER ENGLISH - 6 Changing Display from Meters to Feet During Calibration you will be able to switch the displayed length from meters to feet by simply pressing the MODE key. Press the ON/OFF 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.

MICROSCANNER ENGLISH - 8 MICROSCANNERTM 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 representation, 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.
10BaseT Cable unshielded (2 pair, 4 wires) Token Ring shielded (2 pair, 4 wires) Below are examples of wiring faults. The FAULT indicator will be displayed and the numerical wire indicators will blink. Reversed: Pair 3 - 6 Crossed: Pairs 4 - 5, 3 - 6 Split Pair Note: If a cable is wired correctly, pin-to-pin, but there is a split pair, Wiremap will display SPLIT PAIR. For example a wire from the 1 - 2 pair could be twisted with a wire from the 3 - 6 pair.
MICROSCANNER ENGLISH - 10 If the wire does not go to the far end, the numerical indicator for the open will be left blank. The word Open will be displayed. Shorted pairs are indicated with a connecting bracket, and the word Short will be displayed. Open: Pair 4 - 5 Short: Pair 1 - 2 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.
Length The Length function measures the full length of a twisted pair or coaxial cable. Twisted pair: If you are measuring standard pair length, MICROSCANNER will determine whether the cable is open, shorted, or connected to a hub. 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 length screen, press the MODE key until the word LENGTH appears on the screen. The overall cable length will be shown.
MICROSCANNER ENGLISH - 12 Some early model 100TX only network equipment does not generate link pulses and MICROSCANNER will display HUB, the cable length and the word SIGNAL. Network Link Indicator (MICROSCANNER PRO) The Network Link Indicator allows you to find and identify active network 10/100 hubs and confirm to which hub MICROSCANNER is connected. It will blink the hubs status indicator to assist locating a single channel in a busy wiring closet. 1.
activate the blinking Hub light. The word SIGNAL blinks once every two seconds right below the word Hub. Go to the wiring closet to view a light that blinks once every two seconds at the port to which the cable is connected. MICROSCANNER detects the kind of hub it is connected to: 10, 100, or 10/100 alternately will be displayed right after the word Hub. The number is followed by the letters F and/or H as an indication for the hub's full or half duplex capabilities.
MICROSCANNER ENGLISH - 14 3. When MICROSCANNER displays PC and the cable length, press the MODE key to activate the blinking Hub light. Pair Length If ▲▼ are displayed, you will be able to show detailed pair information for each standard conductor pair. 1. Press the ▲ key to display Pair 1 - 2 length. 2. Press the ▲ key again to display the other pair combinations. The pair length is not measured if the cable is too long, connected to a hub, or a wiremap adapter is used.
Coaxial Cabling (MICROSCANNER PRO) Note: This feature is available in the residential version or when using the COAX upgrade kit. MICROSCANNER measures the full length of a 50 and/or 75Ω (Ohms) coaxial cable, e.g. RG-6 and identifies its termination state. 1. Attach the supplied COAX adapter to the MAIN jack (identified on the unit right above the modular 8 jack). 2. Connect the cable to be tested to the COAX adapter jack. 3.
MICROSCANNER ENGLISH - 16 Office Identifier The Office Identifier function allows you to find the termination of an office cable drop from a wiring closet. By inserting the Office Identifier adapters into RJ-45 office wall outlets, MICROSCANNER can identify office locations at the patch panel. The Office Identifier plugs are included in the optional Office Identifier accessory kit. They are uniquely numbered.
Office Identifier (MICROSCANNER PRO) The Office Identifier function allows you to find the termination of a twisted pair and/or a coax cable drop from a distribution panel. By inserting the Office Identifier adapters into wall outlets, MICROSCANNER can identify office locations at the distribution panel. The Office Identifier plugs are included in the optional Office Identifier accessory kit.
MICROSCANNER ENGLISH - 18 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.
