Basic Maintenance
Warning
To avoid shock, remove the test leads and any input signals before opening the case or replacing
the battery or fuses.
Opening the Meter Case
Caution
To avoid unintentional shock circuit, always place the uncovered Meter assembly on a protective
surface. When the case of the Meter is open, circuit connections are exposed.
To open the Meter case, refer to Figure 1 and do the following:
1. Disconnect test leads from any live source, turn rotary switch to OFF, and remove the test
leads from the front terminals.
2. Remove the battery door by using a flat-blade screwdriver to turn the battery door screws turn
counter-clockwise.
3. The case bottom is secured to the case top by four screws and two internal snaps (at the LCD
end). Using a Phillips-head screwdriver, remove the four screws.
Replacing the Battery
The Meter is powered 1.5V x 2 batteries.
To replace the battery, refer to Figure
9
Testing Fuses (only for MM1-2 / MM1-3)
To test the internal fuses of the meter.
1. Turn the rotary selector switch to the position.
2. To test FS1, plug a test lead into VHz input terminal, and touch the probe to the A input
terminal. The display should indicate between 0.0 to 0.2. FS1 (10A 500V) (Bussmann BBS-1
recommended). If display reads higher than 0.2, replace the fuse.
Fuse Replacement (only for MM1-2 / MM1-3)
Refer to the following figure to replace fuse:
Use only a fuse with the amperage, interrupt, voltage, and speed rating specified.
Fuse rating: 10A, 500V, Fast
Replacing Fuses (only for MM1-2 / MM1-3)
Warning
To avoid electrical shock, remove the test leads and any input signals before replacing the
battery or fuses. To prevent damage or injury, INSTALL ONLY quick acting fuses with the
following Amp/Volt current interrupt rating:
FS1 Fuse: 10A, 500V, FAST. Minimum interrupt rating 10,000A
Cleaning
Warning

Performance Tests
The following performance tests verify the complete operability of the Meter and check the
accuracy of each Meter function against the Meter’s specifications.
Accuracy specifications are valid for a period of one year after calibration, when measured at an
operating temperature of 18°C to 28°C and A maximum of 80% relative humidity.
To perform the following tests, it is not necessary to open the case, no Adjustments are
necessary. Merely make the required connections, apply the designated inputs, and determine if
the reading on the Meter display falls within the acceptable range indicated.
If the Meter fails any of these tests, it needs calibration adjustment or repair.
Testing the Display
Press “HOLD” key while turning the Meter on from the “OFF” position to hold the display in the
Display Test Mode. Compare the display with the example in Figure 2. Turn off the meter to
escape the test mode.

Testing the Capacitance Function
The Meter measures capacitance by charging the capacitor with a known Direct current,
measuring the resultant voltage, and calculating the capacitance. If the same capacitance is
measured on an impedance bridge, a different reading may result. This variance is likely to be
Greater at higher frequencies.
To verify the accuracy of the capacitance measuring function, do the Following :
1. Apply the Capacitor to the VΩHz and COM inputs on the Meter. For steps 1 through 7 in Table
4.
2. Turn the rotary switch
3. Compare the reading on the Meter display to the reading in Table 4.
Note : The meter selects the proper range automatically. Each measurement takes about one
second per range, 2mF takes about 4.5 seconds.
4. If the display reading falls outside of the range shown in Table 4, the Meter does not meet
specification.
