Capacitance (MFD)
SC240 and SC260 only
Start and run capacitors are one of the most failure prone
components in a HVACR system. Disconnect from power and resistors
between terminals. Discharge capacitor before testing. If dIS.C is
displayed, capacitor is not fully discharged. Set to

/MFD to test diodes for proper forward
and reversed-biased functions. Press SELECT twice to manually select
the diode test. A constant beep and green LED indicate continuity.
Test current: 1.0mA (Approx.) Accuracy: ±(1.5% + 5)
Open circuit volts: 3.2VDC typical
Visual indicator: Green LED Audible beep: <0.03V
Auto Select Threshold: Forward voltage drop <0.8V (SC240/SC260
only)
Overload Protection: 600VDC or 600VAC rms
Non Contact Voltage (NCV)
Use NCV to check for 24VAC from a thermostat or live voltage up
to 600VAC. Always test on a known live source before using. A three
segment graph and RED LED will display the presence of voltage. The
audible beep increases from intermittent to continuous as intensity of
field (EF) increases.
AC Voltage Detection Range: 24VAC to 600VAC (50-60Hz)
Amps AC (AAC)
Test any isolated power line, compressor or capacitor wire. True
RMS on SC260 only.
Ranges: 40A, 400A Resolution: 0.01A Crest factor: ≤ 3
Accuracy: ±(2.0% + 10) 50-60Hz Jaw Opening: 1.2in (30 mm)
True RMS: model SC260 only Overload Protection: 400AAC
!
Note: AAC through the clamp and voltage through the test
leads can be measured simultaneously. However, if only AAC is
measured through the clamp, test leads and thermocouple must
be unplugged from the meter.
MicroAmps DC (µADC)
SC220 only
Microamps for flame rectifier test on a heater control. Connect
leads between flame sensor probe and control module and turn
heating unit on to read µA measurement. When the flame is on,
there should be a measurable µADC signal, typically under 10µADC.
Compare measurement to manufacturer’s specification to determine
if replacement is necessary.
Ranges: 400µA, 4000µA Resolution: 0.1µA
Accuracy: ±(1.0% + 2) Voltage burden: 1V, 8V on 4000µA
Overload Protection: 600VDC or 600VAC rms

Temp. Calibration
For accuracies of ±1°F, calibrate to a known
temperature. A glass of stabilized ice water
is very close to 32°F (0°C) and is usually very
convenient but any known temperature can be
used. For SC240/SC260 models only.
1. Select the °F °C range.
2. Plug thermocouple to be
calibrated into the Type K jack.
3. Unscrew A and B and remove
the battery cover.
4. Stabilize a large cup of ice
water. Stir the ice with the
water until temperature stays
at a stable value.
5. Immerse the thermocouple
probe and let it stabilize. Keep
stirring water to prevent micro-
environments.
6. Do not let the thermocouple
come in direct contact with ice.
7. Use a small screwdriver to
adjust calibration pot C below
the battery as close to 32°F
(0°C) as you would like.
Note: J1-J2 switch is for auto-
calibration purposes only. Not
intended for use in the field.
Safety Features
1. Bright LED and beeper warn when testing volt-
ages >16VAC/35VDC. High Voltage warning.
2. Switch to the NCV function (non contact volt-
age) and point clamp claw towards suspected
voltage source. Monitor the bright RED LED
and beeper to see if the source is “hot.”
3. Temperature switch prevents the thermo-
couple plugging in while measuring voltage.
