The Minimax and Minimax-M hand-held meters incorporate state of the art technology
to make signal level measurement faster and easier than ever before. Auto-calibration,
using a built-in white noise source, corrects every measurement for frequency response,
attenuator setting, and temperature. Keypad tuning, an autoranging attenuator and dig-
ital readouts allow novice users to take accurate, foolproof readings with minimal train-
ing.
The full keypad provides instant access to all channels and frequencies. Dedicated keys
for all functions eliminate the need to look up hidden commands or menus. Advanced
features include C/N, Hum, Favorite Channel Programming, and ▲Picture-Audio.
Minimax-M Models have been tailored for the MMDS installer. An extra battery provides
switchable 18 V power at the F connector for powering the downconverter and a
microammmeter makes antenna alignment easy. A special channel plan designed for
MMDS is standard on these models.
All models are programmed with the most commonly used channel plans. Additional
standard and custom plans are also available.

MINIMAX models are powered by 15 AA high energy nicad batteries. The 15 cells are
split into one pack of 7 and one pack of 8. MINIMAX-M models are powered by 15 Sub-
C high energy nicad batteries (1 pack). The batteries in your new meter may not be fully
charged when you receive it.
Check the battery voltage before u ing your meter and recharge if nece ary.
Charge time is aproximately 14 hours.
Use only the proper Sadelco Charger:
AC Charger: T60 for 110V
T60 for 220V
The operating voltage range is approximately 20 Volts to 15 Volts. At 17 Volts, the meter
will beep and begin flashing a Lo Bat warning. Under average operating conditions, you
will have about 30 minutes left for both models. When the charger is plugged in, the dis-
play will show 24 V.
TO CHECK THE BATTERY VOLTAGE
Di connect the charger.
Minimax Model :
Press the BAT key. The battery voltage will be displayed on the left side of the display.
The Minimax will operate for a minimum of 3.5 hours continuously with a full charge.
(> 16 hours of normal intermittent use)
Minimax-M Model :
Press the HUM/BAT key. The Battery voltage will be displayed on the left side of the dis-
play. If this key is held down for 3 seconds, the HUM mode will be activated. To escape,
press SC/CLR.
With the power out on, the Minimax-M will operate for a minimum of 4 hours continuously
with a full charge (>16 hours of normal intermittent use), or 7 hours with the power out
off.
Use of lights, maximum volume, or extremely cold temperature will reduce operating
times.

USING THE ELAPSED TIME INDICATOR
To help maximize battery power, we have included an elapsed time indicator which
appears on the right side of the LCD whenever battery voltage is displayed.
After fully charging the meter, re et the timer to zero by pre ing: decimal point, BAT.
Now, whenever the meter is used, the operating time is accumulated.
After every 30 minutes of elapsed time, the meter will beep and display the total elapsed
time and the battery voltage for 4 seconds.
AUTOMATIC SHUTOFF
To increase the effective battery life, all Minimax and Minimax-M models are equipped
with an automatic shutoff circuit. It is factory set at 5 minutes. Any keypad entry during
the 5 minutes resets the clock. To turn the meter on after an auto shutoff, press and hold
the ON/OFF key.
To deactivate the auto shutoff: Press decimal point, 00, NT

Using Sadelco’s patented white noise calibration technology in conjunction with stored
correction tables, auto-calibrations are performed every two minutes of operation.
Auto-calibrations are also performed:
when the meter is turned on
when a new channel is tuned
when the autoranging attenuator switches pads in or out
when the internal temperature changes more than 8 degrees
You may notice a momentary delay and hear the clicking of the attenuator during an
Auto-calibration. The display is frozen during this time.

GENERAL PROCEDURE
1. Turn power ON.
2. Check battery.
3. Connect RF signal to input.
4. Select Channel or Frequency via keypad.
5. Select Picture or Audio carrier using ▲PA Key.
6. Read signal level on right side of LCD display.
(The microammeter also indicates level on MINIMAX-M models)
AUTORANGING ATTENUATOR
The autoranging attenuator eliminates the need to manually switch pads in or out to
bring the signal level in range. You will hear some clicking as the relays are switched in
and out. If the RF signal is above or below the meter’s range, the LCD will indicate this
by flashing Or (Over Range) or Ur (Under Range). On MINIMAX-M Models, the
microammeter will automatically change ranges as necessary. L Ds indicate the prop-
er scale to read. If the RF signal is above or below the meter’s range, the microamme-
ter will peg right or left respectively.
CHANNEL PLAN SELECTION
Refer to Appendix A for a list of standard channel plans programmed into your meter.
Additional standard and custom plans are available from the factory.
Pre the PLAN key to view the current channel plan on the LCD.
To elect another plan:
1. Press the PLAN key.
2. nter the number of the Plan or scroll to another plan using the UP/DOWN keys.
3. Press the NT key.
4. The meter will tune to Channel 2 Picture carrier of the new plan.
10

TUNING BY CHANNEL NUMBER
1. Press the desired channel number. Leading zeros such as 02 are not necessary.
2. Press CH/FRQ.
By not using a decimal point, the meter automatically tunes to either the Picture or Audio
Carrier of the channel number that was entered.The display will indicate the channel
number followed by a P for Picture or an A for Audio and the signal level.
xample: CH 2P -8.7
If an invalid channel number is selected, the meter defaults to the previously tuned
channel or frequency.
AUTOMATIC ▲PA CALCULATION
To automatically toggle between Picture and Audio carriers of the same channel and cal-
culate the ▲(difference) between them:
1. Tune to a Picture carrier.
2. Press the ▲PA key to switch to the Audio carrier.
3. Press the ▲PA key again to calculate and display the ▲PA.
4. Press the ▲PA key again to return to the Picture carrier.
Note: the ▲PA function can not be activated in the digital channel mode.
TUNING BY FREQUENCY
1. nter the desired frequency number including a decimal point.
2. Press CH/FRQ.
The meter will tune and display frequencies in 125 KHz steps. If the entered frequency
does not fall on one of the 125 KHz steps, the meter will tune to and display the closest
step. Offsets up to +/-40 KHz are read with negligible error.
You must enter a decimal point even for frequencies that are whole numbers such as
54.00 MHz. The decimal point tells the meter to tune to a frequency instead of a chan-
nel. You do not have to enter zeros after the decimal point.
TUNING USING THE UP/DOWN KEYS
The UP/DOWN keys function in all three tuning modes: Channel, Frequency, and
Favorite Channel.
In the Channel Mode, each press of the UP or DOWN key initiates a 6 MHz shift to the
next carrier (7 MHz or 8 MHz in some uropean Tables).
In the Frequency Mode, each press of the UP or DOWN key initiates a 125 KHz shift.
11

TUNING USING THE UP/DOWN KEYS (Continued)
In the Favorite Channel Mode, each press of the Up or Down key initiates a jump to the
next programmed channel or frequency.
In all modes, when the top or bottom of the tuning range is reached, it will loop around
continuously.
SWITCHING BETWEEN CHANNEL AND FREQUENCY
When tuned to a channel, pressing the CH/FRQ key will display the frequency of that
channel and switch the meter to the Frequency Mode.
When tuned to a frequency, pressing the CH/FRQ key will display the channel number
of that frequency and switch the meter to the Channel Mode. If no channel number
exists for a particular frequency, the meter will tune to either the closest picture or audio
carrier depending on which mode the ▲PA is in.
TUNING SUB BAND, UHF, AND SPECIAL CHANNELS
Some channel plans contain more than one channel with the same channel number. In
order to provide direct keypad access to all channels, we have added an additional num-
ber in front of the channel number in some cases. Refer to Appendix A for complete
channel listings.
Sub Band channel , T07 - T13 can be acce ed directly by entering 707 - 713.
In the MMDS Channel Plan, UHF Channel 14 - 70 are elected directly by entering
914 - 970.
In the AIR Channel Plan, UHF Channel are elected by entering 14 - 70.
For example:
The MMDS Channel Plan contains:

On MINIMAX-M models, the HUM function shares a key with the BAT check. This
requires the operator to hold the key down for 3 seconds to activate HUM. During this
3 seconds, the battery condition is displayed. On the MINIMAX models, the HUM key is
separate so it needs only to be pressed to activate HUM.
Measurement of HUM (low frequency disturbance) can be made on any active audio car-
rier or unmodulated CW signal. A minimum signal level of -20 dBmV for the Minimax and
-11 dBmV for the Minimax-M is required for Hum measurement.
To mea ure HUM:
1. Tune to the Picture or Audio carrier of the channel you wish to measure or tune to
the frequency of the CW signal.
2. Press HUM (Hold for 3 seconds on MINIMAX-M models).
3. HUM will be displayed in %. (If Hum is >6%, the display will flash 6%).
4. Press SC/CLR to return to signal level measurement mode.
Note: If you tune to a picture carrier using a channel number, the meter automatically
switches to the corresponding audio carrier before making the HUM measurement. If
you tune to a picture carrier using a frequency number, the meter remains at that fre-
quency and attempts to measure HUM. This feature allows HUM measurement of a CW
signal at any frequency but will give incorrect HUM measurements if the entered fre-
quency is an active picture carrier.
Note: Hum cannot be activated in the digital channel measurement mode.

Noise measurements on active cable systems are effected by many factors such as car-
rier sidebands, harmonic products, and spurious beats.
Ideal measurements are made by using a band pass filter to isolate the channel being
tested and by shutting off the carrier before making the noise measurement. Refer to the
NCTA recommended practices for guidelines on making the best measurements under
various conditions.
Use of a low noise preamplifier is recommended when signal levels are below +20
dBmV.
Method One
This is the preferred method when conditions permit.
1. Connect a band pass filter between the test point and the meter.
2. Tune to the desired picture carrier using channel number or frequency.
3. Press the C/N key. The meter stores the carrier level.
4. If you tuned using a channel number the meter will switch to the corresponding fre-
quency and begin to flash. If you tuned using a frequency, the meter will remain in
the frequency mode and begin to flash.
5. Shut off the carrier.
6. Press the NT key. The meter reads the noise level, adds a correction factor, cal-
culates and displays the C/N ratio.
7. Press SC/CLR to return to the signal level mode.
Method Two
If you cannot turn off the carrier.
1. Connect a band pass filter between the test point and the meter.
2. Tune to the desired picture carrier using channel number or frequency.
3. Press the C/N key. The meter stores the carrier level.
4. If you tuned using a channel number the meter will switch to the corresponding fre-
quency and begin to flash. If you tuned using a frequency, the meter will remain in
the frequency mode and begin to flash.
5. Use the UP/DOWN keys or number keys and CHN/FRQ to search for the lowest
noise level near the channel. This is often 1.5 MHz below the carrier but will
depend on the shape of your filter.
6. When you have found the lowest noise reading, press NT. The meter reads the
noise level, adds a correction factor, calculates and displays the C/N ratio.
7. Press SC/CLR to return to the signal level mode.
14

9,68$/ $55,(57212,6(5$7,2
RQWLQXHG
Method Three
When you cannot shut off the carrier and you do not have a band pass filter.
1. Locate a channel that does not have another channel below it, or where there is a
band guard. Tune to the picture carrier of that channel using channel number or
frequency.
2. Press the C/N key. The meter stores the carrier level.
3. If you tuned using a channel number the meter will switch to the corresponding fre-
quency and begin to flash. If you tuned using a frequency, the meter will remain in
the frequency mode and begin to flash.
4. Use the UP/DOWN keys or number keys and CHN/FRQ to search for the lowest
noise level near the channel. This is often 1.5 MHz below the carrier.
5. When you have found the lowest noise reading, press NT. The meter reads the
noise level, adds a correction factor, calculates and displays the C/N ratio.

models. Not all models contain all plans. Models with limited frequency ranges contain
only the appropriate portions of the plans.
Since some plans have more than one channel with the same channel number, the first
column lists the keypad entry for direct access to a channel and the second column lists
the channel number as it is displayed on the LCD.
Additional standard and custom channel plans are available from the factory.
