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
To change setting to 10 minutes: Press decimal point, 10, NT
To return to 5 minutes: Press decimal point, 05, 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.
