Capacitance Measurement - Bahco BMMTRS1 Original Instructions Manual

ENGLISH
Some tips for measuring resistance:
• The measured value of a resistor in a circuit is often different from the resistor's rated value. This is
because the Meter's test current flows through all possible paths between the probe tips.
• In order to ensure the best accuracy in measurement of low resistance, short the test leads before
measurement and memory the test probe resistance in mind. This necessary to subtract for the
resistance of the test leads.
• The resistance function can produce enough voltage to forward-bias silicon diode or transistor junc-
tions, causing them to conduct. To avoid this, do not use the 60MΩ range for in-circuit resistance
measurements.
• On 60MΩ range, the meter may take a few seconds to stabilize reading. This is normal for high
resistance measuring.
• When the input is not connected, i.e. at open circuit, the figure "OL" will be displayed for the over-
range condition.

3.2.3 Capacitance measurement

To avoid electrical shock and/or damage to the instrument, disconnect circuit
power and discharge all high-voltage capacitors before measuring capacitance.
Use the dc voltage function to confirm that the capacitor is discharged.
The Meter's capacitance ranges are 6.000nF, 60.00nF, 600.0nF, 6.000µF, 60.00µF, 600.0µF,
6.000mF, 60.00mF.
To measure capacitance (set up the Meter as shown in Figure 3-3):
1. Set the rotary switch to Ω
2. Press the SELECT key to select capacitance Test
3. Connect the black and red test leads to the COM and
capacitor test lead).
4. Connect the test leads to the capacitor being measured and read the displayed value.
