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.
˙Do not apply more than the rated voltage, as marked on
Meter, between terminals or between any terminal and
earth ground.
˙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.
˙Discharge all high-voltage capacitors before testing.
˙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.

Measuring L/C/R/DCR
• Press the L/C/R/DCR button to select the measuring function.
• Press the L/C/R/DCR button for 2 seconds to enter the Auto
L/C/R function.

10
Measuring D/Q/ESR/
• Press the D/Q/ESR/button to select the measuring function.

11
Select test Frequency
• Press the FREQ button to select the test frequency.
• The 100KHz test frequency is only at LCR1703.

12
Select Series / Parallel measuring function
• At the L/C/R measuring function, it defaults to Auto Series /
Parallel measuring function.
• Press the SER/PAL button to select the measuring function.

13
Select Display Count
• Press the 2000 /20000 button to select the display count.
Zero
The Zero mode records the current input value as reference and
appears on the sub display. The after input values will subtract
the reference value and display on the main display. To use the
Zero mode, follow the steps below.
1. Press the Zero button to enter Zero mode. The “Δ” appears
on the display.
2. Press the Zero button again to record a new input value as
reference.
3. Press the Zero button for 2 seconds to exit this mode.

14
The MAX/MIN mode records the maximum and the minimum
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.
To use the MAX/MIN mode, follow the steps below.
1. Press the MAX/MIN button to enter the MAX/MIN mode.
The “MAX” appears on the display, the maximum value on
the main display and the current value on the sub display.
2. Press the MAX/MIN button to select the MAX or MIN display.
3. Press the MAX/MIN button for 2 seconds to exit this mode.
Note : This function is only at LCR 1703.
Display Hold
• Press the HOLD button to hold the reading of the meter, press
the button again to return.

Calibrate
In order to achieve the best measuring result, calibration is
must. To calibrate the meter, press the CAL button.

16
When “OPEn” appears on the sub display, make the terminal or
the SMD test probe open, and press the CAL button to start
open calibration. About 30 seconds later, the result of the open
calibration appears on the main display. If the result is pass,
press the CAL button to next step. If the result is fail, press the
CAL button to exit the function.

17
When “Srt” appears on the sub display, make the terminal or the
SMD test probe short, and press the CAL button to start short
calibration. About 30 seconds later, the result of the short
calibration appears on the main display. If the result is pass,
press the CAL button to complete the calibration. If the result is
fail, press the CAL button to exit the function.

18
Sorting
To check the accuracy of the part, press the SORTING button
to enter the sorting mode. The sorting result appears on the
main display, and the current value appears on the sub display.

19
The default sorting standard value is the current value, and the
default tolerance is ±1.0%.
Setup Sorting Standard
To setup the sorting standard value, follow the steps below.
1. Press the SETUP button to enter the setup mode.
2 Press  and  button to setup the range of the standard
value. Then press the ENTER button to save the setup
value and enter the next step.
3. Press △ ,,  and  button to setup the standard value.
Then press the ENTER button to save the setup value and
enter the next step.
4. Press  and  button to setup the tolerance value. Then
