Making Basic Measurements
Preparation and Caution Before Measurement
: Observe the rules of Warnings and Cautions
.
When connecting the test leads to the DUT (Device Under
Test) connect the common (COM) test lead before connect- ing the live lead ; w hen removing the test leads removing the test live lead before removing the common test lead.
The figures on the following pages show how to make basic measurements.
TEST EQUIPMENT RISK ASSESSMENT (UK RECOMMEN­DATION)
Users of this equipment and/or their employers are reminded that Health and Safety Legislation require them to carry out valid risk assessments of all electrical work so as to identify potential sources of electrical danger and risk of electrical injury such as from inadvertent short circuits. Where the assessments show that the risk is significant then the use of fused test leads constructed in accordance with the HSE guidance note GS38 "Electrical Test Equipment for use by Electricians" should be used.
12
Measuring AC/DC Voltage And Frequency
13
Note – When measuring voltage, the Meter acts like a 10MΩ impedance in parallel with the circuit under test. This loading effect of the 10MΩof the Meter can cause measurement errors, loading efffect error, Especially in high impedance cir­cuits. For example : A 1.1M impedance circuit will cause a –10% measuring error. The error percentage of the loading effect of the Meter is expressed as following :
- Zcircuit
Zcircuit + 10M
%
100 x
The non-zero display reading is normal when the meter test leads are open, which will not affect actural measurement accuracy. The Meter will show zero or close to reading when the test leads are shorted. In reading AC voltage or current, reading-settling time increases to several seconds at the low end of AC voltage and current ranges in rms models.
14
Measuring Resistance
 Caution
To avoid possible damage to the Meter or to the equip­ment under test, disconnect circuit power and discharge
all high-voltage capacitors before measuring resistance.
Note – The Meter provides a open voltage –1.5V to the circuit under test that cause the diode, transistor junction to conduct so it is batter to disconnect the resistance from the
circuit to get a correct measurement.
The resistance of test leads is about 0.1Ω ~ 0.2Ω. To test the leads resistance, touch the probe tips together. For accuracy measurement in low resistance use the relative features to zero the test leads resistance.
15
Testing for Diode and Continuity
Diode :
Continuity :
Good! Good!
Bad!
 Caution
For in-circuit test, turns circuit power off and Discharge the high-voltage capacitors through an appropriate resistance load.
16
Measuring DC mA, AC mA, DC A, AC A Current And Frequency
Note – Use the diode test to check the semiconductor junction is good or bad. The Meter sends a current through the semiconductor junction to measures the voltage drop across the junction. A good junction drops between 0.4 V to 0.9 V.
Never attempt an in–circuit measurement where The open–circuit potential to earth potential is great than 500V, or example a 3-phase system measurement, you may damage the Meter or to be injured.
 Warning
17
To avoid possible damage to the Meter or to the equip-
ment under test, check the Meter’s fuses before measur-
ing current. Use the proper terminals, function, and range for
your measurement.
Never place the probes across (in parallel with) any
circuit or component when the leads are plugged into the
current terminals.
When measuring current, the Meter acts like a impedance
such as 5Ω at AC/DC mA (0.005Ω at DC / AC A) in series
with the circuit.
This loading effect of the Meter can cause measurement
errors, loading effect error, especially in low impedance
circuits.
For example : To measure a 5Ω impedance circuit at DC / AC
mA range will cause a –50% measuring error. The error per-
centage of the loading effect of the Meter is expressed as
following :

Making Basic Measurements
Measuring Hz / RPM
Note – Connect the red test lead to the “
VΩHz ” terminal and the other (black) test lead to the “COM” terminal. Set the rotary function selector to “Hz RPM” position to meas­ure the frequency or RPM with the blue switch. Connect the test leads to the circuit to be measured.
19
Measuring Capacitance
To avoid possible damage to the meter or to the equip­ment under test, disconnect circuit power and discharge all high-voltage capacitors before measuring capacitance. Use the DC voltage function to confirm that the capacitor discharged.
Note– To improve the measurement accuracy of small value capacitor, memory the reading with the test leads open than substracts the residual capacitance of the Meter and leads from measurement.
