Inductance, Capacitance, Resistance Selection
The L/C/R key selects the primary parameter measurement function. Each press of the key will
select either inductance (L), capacitance (C) or resistance (R) along with the proper units of H
(henries), F (farads) or
(ohms) in the main large display.
Quality, Dissipation, Resistance Selection
The Q/D/R key selects the secondary parameter measurement function. Each press of the key will
select either the quality (Q) or dissipation (D) indicators or resistance () units in the small
secondary display.
Hold and Backlight Selection
The HOLD >2sec key selects the Hold feature and also enables the display backlight.
Press the key and the H indicator will appear in the display and the last reading will “freeze” in the
display. Press the key again and the reading will begin to update again.
Press and Hold the key for 2 seconds and the display backlight will turn-on. To extinguish the
backlight, press and hold the key again for 2 seconds or wait 1 minute for it to automatically disable.
Minimum, Maximum and Average Selection
The MAX MIN key selects the recording function. Press the key and the “R“ indicator will appear in
the display and the meter will begin recording the minimum, maximum and average measured
values. When this mode is entered, the auto power off and the function keys are disabled.
Max-Min operation
1. Set all the function parameters for the test.
2. Press the MAX MIN key. The “R“ indicator will appear and a “beep” will sound after
approximately six seconds. Two “beeps” will sound every time the max or min is updated.
3. Press the MAX MIN key. The “MAX” indicator and the maximum recorded value will appear in
the display
4. Press the MAX MIN key. The “MIN” indicator and the minimum recorded value will appear in
the display
5. Press the MAX MIN key. The “MAX - MIN” indicator and the difference between the maximum
- minimum value will appear in the display
6. Press the MAX MIN key. The “AVG” indicator and the average of the recorded values will
appear in the display.
7. Press and hold the MAX MIN key for 2 seconds to exit the mode.
Notes:
The average value is a true average and averages up to 3000 values. If the 3000 limit is exceeded,
the AVG indicator will flash and no further averaging will take place. The max and min values will
continue to update.
If the HOLD key is pressed during min max recording, the recording is halted until the HOLD key is
pressed again.
Relative Mode
The relative mode displays the difference between the measured value and the value of a stored
reference.
1. Press the REL key to enter the Relative mode.
2. The value in the display when the REL key is pressed will become the stored reference value
and the display will indicate zero or a value close to zero (since the measured value and the
reference value are the same at this point).
3. All subsequent measurements will be displayed as a value relative to the stored value.
4. The reference value may also be a value that was stored into memory using the SET Relative
procedure (see the Setting a Relative Reference paragraph).
5. To use the SET relative value, press the SET key while in the Relative mode.
6. To exit the Relative mode, press and hold the REL key for 2 seconds.
