Safety Information
Understand and follow operating instructions carefully.
Use the meter only as specified in this manual; otherwise,
the protection provided by the meter may be impaired.

 WARNING
Identifies hazardous conditions and actions that could cause
BODILY HARM or DEATH

CAUTION
Identifies conditions and actions that could DAMAGE the meter
or equipment under test
 WARNING
˙When using test leads or probes, keep your fingers behind
the finger guards.
˙Remove test lead from Meter before opening the battery
door or Meter case.
˙Use the Meter only as specified in this manual or the protec-
tion by the Meter might be impaired.
˙Always use proper terminals, switch position, and range for
measurements.
˙Verify the Meter’s operation by measuring a known voltage.
If in doubt, have the Meter serviced.
˙Do not apply more than the rated voltage, as marked on
Meter, between terminals or between any terminal and
earth ground.
˙Only replace the blown fuse with the proper rating as speci-
fied in this manual.
˙Use caution with voltages above 30 Vac rms, 42 Vac peak,
or 60 Vdc. These voltages pose a shock hazard.
˙To avoid false readings that can lead to electric shock and
injury, replace battery as soon as low battery indicator.
˙Disconnect circuit power and discharge all high-voltage
capacitors before testing resistance, continuity, diodes, or
capacitance.
˙Do not use Meter around explosive gas or vapor.
˙To reduce the risk of fire or electric shock do not expose this
product to rain or moisture.

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 (mA) test lead before
connecting the live lead ; when 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.

Measuring Insulation Resistance
Select test voltage
Press the Range button to select the test voltage
(50V / 100V / 250V / 500V / 1000V)
Lock test voltage
Press the Hold button to lock the test voltage. Press the button
again to cancel the lock mode.
Make the reading stably
Press the Blue button to make the reading stably, the “Smooth”
appears on the display. Press the Blue button again to cancel
this mode.

Measuring Insulation Resistance
=
Insulation tests should only be performed on dead circuits.
Check the fuse before testing. To measure insulation resis-
tance, follow the steps below.
1. Insert test probes in the “⊕“ and “ “ input terminals.
2. Turn the rotary switch to Insulation position.
3. Press the Range button to select the test voltage.
4. Connect the probes to the circuit.
5. Push and hold the Test button to start the test.
The “Test” and ””appear on the display. The secondary
display shows the test voltage applied to the circuit under
test. The primary display shows the resistance.
6. Keep the probes on the test points and release the Test
button. The resistance reading appears on the primary
display until a new test is started or a different function or
range is selected or > 30 V is detected.

10
Measuring Frequency for ACV, ACmV and ACmA
The meter measures the frequency of a voltage or current signal
by counting the number of times the signal crosses a threshold
level each second. To measure frequency, follow the steps
below.
1. Turn the rotary switch to V, mV or mA position.
2. Press the Hz button to measure the frequency.
3. Press the Hz button or change the rotary switch position
to exit this function.
Display Hold
In the Hold mode, the meter holds the reading. To use the Hold
mode, follow the steps below.
1. Press the Hold button to activate Hold mode. The “ Hold ”
appears on the display.
2. Press the Hold button, Blue button, Range button or change
the rotary switch position to exit this function.

11
The “MIN/MAX/AVG“ mode records minimum and maximum
input values. When the inputs go below the recorded minimum
value or above the recorded maximum value, the meter beeps
and records the new value. MIN/MAX/AVG mode can also
calculate an average of maximum and minimum.To use the
MIN/MAX/AVG mode, follow the steps below.
1. Press the “MIN/MAX“ button to activate MIN/MAX/AVG
mode. The “MIN MAX” blinks on the display.
2. Press the “MIN/MAX“ button to step through the present
readings, maximum, minimum and average (AVG).
