POWER ON/OFF
To turn the M1 on press the Power ON button. Upon power-up, an LCD self-test will be displayed
for two seconds. To turn the M1 off press the Power OFF button.
GATE
The GATE button is used to change the measurement period of the M1. The GATE button is also
used to scroll forward through the M1’s 100 memories. To see the different GATE times for the M1
turn to the specifications page.
RANGE
The RANGE button is used to change the three different M1 ranges. A, B and Prescale. The RANGE
button is also used to scroll backward through the M1’s 100 memories.
1.
A
1Meg Ohm High Impedance Range: 1Meg Ohm range is indicated with a “A” in the top
right hand corner of the LCD. The frequency range of the 1Meg Ohm range is 50Hz-40MHz. This
range is useful for in-circuit measurement using a scope probe
2.
B
.50 Ohm Direct 250MHz Range: Direct range allows for the fastest count from 10 MHz-
250MHz. 50 Ohm Direct range is indicated with a “B” in the top right corner of the LCD.
3.
Prescale
Prescale Range: Prescale range is used to count the frequency range from
30MHz-2.8GHz.
The 2.8GHz (Prescale) range completely covers all VHF and UHF communications so it is fine to
leave the M1 in this range all the time. The advantage of the direct 250MHz range is that it is much
faster to respond and it gives a measurement with more digits of resolution. If you are frequency
finding and do not know the range to look it is best to use the 2.8GHz range. If you know the
approximate frequency being transmitted is less than 250MHz then use the direct 250Mhz range.
