Measuring Resistance; Measuring Temperature; Testing Batteries - Velleman DVM860BL Mode D'emploi

REMARKS
• Use an AC clamp (e.g. AC97) to measure AC currents
• The LCD displays the overrange indication "OL" if the measured value is too high for the range you are using.
Select a higher range.
• Place the range selector in the highest position if the value to be measured is unknown beforehand.
• Install the same range on the DVM860BL and the AC clamp. If the ranges do not match exactly, be careful not to
exceed the limit values on the DVM860BL and the AC clamp of your choice:
a. the sensitivity of the 200A range is 200mV, that of the 2000A range is 2V. The sensitivity of the matching
clamp should be 0.1A/0.1mV in order to make sure that the value you read out is also the measured value.
b. If your clamp has a low sensitivity (0.1A/0.01mV), the indicated value will be 10 times lower than the
measured value e.g. the measured current is 100A, then the indicated value will be 10.0A
c. If your clamp has a high sensitivity (0.1A/1mV), the indicated value will be 10 times higher than the
measured value e.g. the measured current is 10A, then the indicated value will be 100.0A

6.14. Measuring Resistance

WARNING
Disconnect the circuit to be tested and make sure that all capacitors are fully discharged before measuring the in-
circuit resistance.
1. Connect the black test lead with the COM jack and the red test lead with the INPUT jack.
2. Select the desired Ω range with the range switch. Auto or manual range selection can be installed with the
RANGE button.
3. Connect the test leads with the resistance being measured.
4. Read the value from the LCD.
REMARKS
• The LCD displays the overrange indication "OL" if the measured value is too high for the range you are using.
Select a higher range.
• The meter may need a few seconds to display a stable reading when measuring resistances > 1MΩ.
• The overrange indication "OL" is displayed when the input is not connected e.g. in case of an open circuit.

6.15. Measuring Temperature

WARNING
Do not connect the thermocouples with electrical circuits in order to avoid electroshocks.
1. Put the range switch in the TEMP position.
2. Select °C or °F with the FUNC. button.
3. The LCD displays the current environmental temperature.
4. Use a "K"-type thermocouple: Insert the black plug in the COM jack and the red one in the INPUT jack. Touch the
test surface or test object with the thermocouple.
5. Read the value from the LCD.

6.16. Testing Batteries

1. Connect the black test lead with the COM jack and the red test lead with the INPUT jack.
2. Place the range switch in the correct position depending on the voltage of the tested battery (1.5V, 3V, 9V).
3. Connect the test leads with the battery in question.
4. Read the measured value from the LCD. The polarity of the red lead connection is also indicated.
