Milwaukee 2237-20, 2236-20 manual Danger, DC Voltage

DC Voltage

DANGER To avoid electrical shock: Never make measurement on a circuit in which voltage over DC600V exists.

Do not use with the Battery Cover removed. Keep fingers away from jaws during mea- surements.

1. Set the Rotary Dial to position.

2. Connect the red test lead to the VΩ terminal and the black test lead to the COM termi- nal.

3. Connect the red

test lead to the positive (+) side and black test

leads to the nega- tive (-) side of the

circuit under test.

The reading is displayed. A reversed connection is indicated as a negative value.

Resistance/Continuity/Capacitance Measurements

DANGER

To reduce the risk of electric shock for Resistance, Continuity, and Capacitance measurements, never use the meter on an energized circuit. Make sure a capacitor is fully discharged before touching or attempt- ing to make a measurement.

Do not use with the Battery Cover removed.

Resistance

CAUTION

After shorting the test leads, the displayed value may not be zero due to the resistance of test leads themselves.

Continuity

1. Set the Rotary Dial to position.

2. Connect the red test lead to the VΩ terminal and the black test lead to the COM terminal.

Confirm “OL” is indicated on the display, and then short- circuit the tips of test leads to make the indication zero.

A buzzer will sound.

3. Connect the test leads to both ends of the conductor

under test. If the resistance under test is 35 ±10Ω or 25Ω or less, the buzzer will sound.

Capacitance

1.Set the Rotary Dial to position.

2.Connect the red test lead to the VΩ terminal and the black test lead to the COM terminal.

3.Discharge capacitor.

4.Connect the test leads to both ends of the capaci- tor under test.

5.The reading is displayed.

DC Current (Cat. No. 2236-20 only)

DANGER To avoid electrical shock: Never make measurement on a circuit in which voltage over AC600V exists.

Do not use with the Battery Cover removed.

Temperature (Cat. No. 2236-20 only)

WARNING

Never connect the Temperature Probe to an energized circuit.

1. Set the Rotary Dial to position.

2. Connect the K-type Tem- perature Probe to the input terminal. The positive (+) side of Probe should be connected to VΩ.

3. Place the probe sensor in the desired location.

4. The reading is displayed.

CAUTION
When the Rotary Dial is set to	, the room
temperature should be displayed. If anything
else is displayed, something may be wrong
with the meter. Stop using the meter imme-
diately.
Worklight LED ON/OFF
To turn the light on and off, press the	button.

HOLD Key

Data Hold Function - Freezes the value on the display. Press the “HOLD” button to freeze the reading. The reading will be held regardless of subsequent variation in input. HOLD is displayed with the reading. To exit Data Hold mode, press the

Non-Contact Voltage Detection (NCVD)

DANGER

The LED may not be displayed due to instal- lation condition of electrical circuit or equip- ment. Never touch the circuit under test to avoid possible danger even if the LED for NCVD is not displayed.

Check the functionality of LED on a well- known power supply prior to measurement. When the LED doesn’t light up, do not make measurement.

NCVD indication is affected by external volt- age, and how the meter is held or placed.

When the meter is on in any function, the non-contact volt- age detector will indicate with a Red LED on the display when an electric field exceeding 90V is detected. Place the edge of the jaw labeled “Voltage Detec- tor” near the electric field.

Over-flow indication

Any time the input exceeds the

measuring range “OL” or “-OL” is displayed.

CAUTION

Clamp the jaws around the conductor under test and press the MIN/MAX button after an appropriate range is selected by Auto-rang- ing function. ZERO and Hz keys are disabled while MIN/MAX Function is active.

MIN/MAX Function

The MIN/MAX function can be used during measurements of AC

1. Set the Rotary Dial to position.

2. Connect the red test lead to the VΩ ter- minal and the black test lead to the COM terminal.

Confirm “OL” is indi- cated on the display, and then short-circuit the tips of test leads to make the indica- tion zero.

1.Set the Rotary Dial to

position. DC mark is displayed.

2.Connect the red test lead to the VΩ ter- minal and the black test lead to the COM terminal. Contact the red test lead to the flame sensor probe and the black test lead to the control module.

HOLD button again.

CAUTION

The Data Hold readings are released when the meter enters Sleep Mode.

Sleep Mode

The clamp meter is automatically powered off in about 20 min after the last Rotary Dial or button operation. To reset, rotate the Rotary Dial to OFF. If the display is still blank when a new Rotary Dial setting is selected, replace the batteries.

The sleep mode is disabled when the MIN/MAX

or DC current, AC or DC voltage, Temperature (2236-20 only), uA DC (2236-20 only), and Resistance. The MIN/MAX function does not work in the Capacitance or Continu- ity measurements.

To measure the minimum or maxi- mum of the function, set the dial to the appropriate dial position and then press the MIN/MAX button to capture the maximum reading. Press the MIN/MAX button again to capture the minimum reading.

3.Connect the test

leads to both ends of the resistor under test.

4.The reading is displayed.

3.Turn on the heating unit. The reading is dis- played.

function is selected.

The clamp meter does use battery power in sleep mode. Be sure to switch the tool to OFF to conserve battery power.

Press the MIN/MAX button to toggle between minimum or maximum. The minimum or maximum reading is displayed and held until the MIN/MAX is turned off by holding in the MIN/MAX button for 2 seconds or changing the Rotary Dial position.
