INSULATION RESISTANCE TSTERS
Introduction
Thank you very much for purchasing this insulation
resistance tester. This is a small, easy-to-operate
insulation resistance tester using a transistor-type, stable
voltage type DC-DC converter. It enables the user to
read promptly and directly the insulation resistance value
of various electric equipment and lines.
1. A small, light-weight and easy-to operate product.
2. Used is a core-magnet type meter which is stable and
little influenced by external magnetic field.
3. It is economical since only four SUM-3 or R6 batteries
can drive the tester.
4. Incorporating the ACV range, it can measure the
voltage of AC line.
5. The measuring switch can be locked, so it is very
handy to make continuous measurements.
6. It incorporates an LED pilot lamp showing ON of high
voltage power sources (500V) and lighting
intermittently, so the user can know precisely whether
or not any voltage exists. It also helps the user avoid
forgetting to turn off the switch when it is locked.

1. Connection of Test Leads Connect the test lead
with probe to the L terminal and the test lead with
clip to the E terminal as shown in Figure 1.

2. Adjustment of Infinity ( ) Scale ... Confirmation
Align the pointer to the infinity line, leftmost of the
MW, scale, by turning the position adjuster in
the center of the indicator, if it doesn't point to it
correctly.

3. Measurement of Insulation Resistance
3-1 Connect the clip to one side of the measured object
and the probe to the other side of the measured
object.
3-2 Turn the control switch from POWER OFF position,
to MWposition and push on PUSH switch , then
the indicator shows the insulation resistance value.
3-3 If the pilot lamp of 500V ON below of the scale
plate, lights intermittently, the tester works properly and
the voltage is correctly impressed on the test point. It
doesn't light, however, if the internal batteries have
worn out or the battery contact is incomplete.
3-4 Set the control switch to MWPOWER LOCK
position for continuous measurements. POWER
switch remains ON regardless of PUSH switch. (The
pilot lamp lights intermittently.)
3-5 Return the control switch to POWER OFF position
after measurement.

4. Check of Internal Batteries.
Set the control switch to BATT CHECK position with
the E and L terminals released.
If the pointer automatically swings to the BATT
scale , both circuit and the internal batteries are
normal. If the pointer points to the left side of the BATT
scale as shown in Fig.2, the batteries have worn out.

Replace them with new batteries. For replacement of
the batteries, refer to page 7.

Replacement of Battery
When replacing battery, loosen the 4 X 15 screw on the
rear case, remove the case, and insert the new batteries
correctly with the right polarity as shown in Fig.3.

5. ACV Measurement
5-1 Connection of the test leads is same as in the
foregoing paragraph.
5-2 Use the control switch in ACV (POWER OFF)
position.
5-3 Connect the lead line tip to the measured point and
read the voltage value in the red 0~600V scale
5-4 This ACV range can be used not only for general
ACV measurements but also for a preliminary
check as to whether or not ACV is impressed on
the measured object, prior to insulation resistance
measurement.
?
Be sure to return the control switch to POWER OFF
position after use. With the control switch to this
position, the current doesn't flow and the batteries
are protected from being exhausted for nothing
even if the measuring push switch is inadvertently
pushed on.
Precaution

lPrecaution for Use
1. E and L Terminals
When the minus side of the measured object is
grounded, plug the test lead into the E terminal.
Make measurement with the E terminal test lead
connected to the ground side. By so doing it is
common that the measured value is indicated at a
smaller value. Safety in use is considered and
promised. For general measurements, use either
polarity of the terminals.
2. If the tester is not used for a long time, be sure to
take out the internal batteries.
3. Don't store the tester in a high temperature and
humidity.
4. Avoid giving any mechanical shock or vibration to
the tester.
5. Don't rub strongly the surface of the indicator cover
with a dry cloth. Should anti-static coating on the
cover be removed, a cloth moistened with anti-static
solvent should be used to clean the cover.
