Manual Ranging - Projecta DT1000 Quick Start Manual

CAPACITANCE MEASUREMENTS
1. Set the rotary function switch to the CAP position.
2. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug
into the positive V jack.
3. Touch the test leads to the capacitor under test.
4. Read the capacitance value in the display.
WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all
capacitors before taking any capacitance measurements. Remove the batteries and unplug the line
cords.
FREQUENCY OR % DUTY CYCLE MEASUREMENTS
1. Set the rotary function switch to the V position.
2. Insert the black test lead banana plug into the negative COM jack and the red test lead banana
plug into the positive V jack.
3. Select Hz or % duty with the Hz/% button.
4. Touch the test probe tips to the circuit under test.
5. Read the frequency on the display.
TEMPERATURE MEASUREMENTS
1. Set the rotary function switch to the TEMP position.
2. Insert the Temperature Probe into the negative COM jack and the positive V jack,
making sure to observe the correct polarity.
3. Select oC or oF with the MODE button.
4. Touch the Temperature Probe head to the part whose temperature you wish to measure.
Keep the probe touching the part under test until the reading stabilizes (about 30 seconds).
5. Read the temperature in the display. The digital reading will indicate the proper decimal point
and value.
WARNING: To avoid electric shock, disconnect both test probes from any source of voltage before
making a temperature measurement.
WARNING: To avoid electric shock, be sure the thermocouple has been removed before changing to
another measurement function.
DATA HOLD AND BACKLIGHT BUTTON
• Press the DATA HOLD button to "freeze" the reading on the indicator.
• "HOLD" will appear when the reading has been "frozen"
• Press HOLD button again to return to normal operation.
NOTE: The HOLD feature will activate when the Backlight is turned on. Press HOLD button again to
exit hold.
• Press the HOLD button for 1 second to turn on the Backlight function.
• Press the HOLD again to turn off the Backlight.

MANUAL RANGING

• Press the RANGE button to go to manual ranging.
• Each press of the RANGE button will step to the next range.
• Range will be indicated by the units and decimal points location.
• Press and hold the RANGE button for 2 seconds to return to normal operation.
NOTE: Manual ranging does not function in the AC Current, Diode and Continuity Check functions.
