Auto/Manual Range Function
(
V,
only)
Autoranging
: The Autoranging function automatically selects the opti-
mum measurement range.
Turning on the power also switches Autoranging on
(
AUTO
lights up).
The range automatically switches up when the display shows 4200
counts or more, and down when the display shows less than 400
counts. (A beep sound is generated when the 3246-60 is switched to a
different range.)
Manual ranging
: Set a range manually.
Turn on the power while pressing the select button (
AUTO
is turned off).
Range selection: Each pressing of the select button selects the next
larger range. After the largest range, pressing the select button again
returns you to the smallest range.
Press and hold down the select button (for about 1 second) to select
AC or DC in manual ranging mode, or select between resistance mea-
surement, continuity check, and diode check in manual ranging mode.
The Manual ranging function is active until the 3246-60 is turned off.
Hold Function [
]
(Available for any measurement function.)
Press
HOLD
to hold the measurement value (
lights up).
In hold mode, the select button operation, the warning beep for voltage
measurement overflow, and beep for diode check judgment are disabled.
To cancel the hold mode: Press
HOLD
again.
Auto Power Save Function [APS]
(Available for any measurement
function.)
When the measurement product is turned on, it automatically enters
Auto Power Save mode (
APS
lights up).
Approximately 10 minutes after completing final operation, the mea-
surement product automatically enters Power Save mode with a beep-
ing sound.
Exiting the Power Save State: turn off the power once.
Disabling Auto Power Saving: turn on the power while pressing
HOLD
. (
APS
is turned off)
Overflow Warning Function [OF]
(
V only)
When the measured value exceeds the maximum indication, a beep
sound is generated (
OF
lights up).
This function is disabled in hold mode.
Penlight/LCD Backlight Function
• ON: Press and hold down
HOLD
. The penlight and LCD backlight
will light. (The hold mode is not influenced)
• OFF: The lights will go off automatically in about 10 seconds. Oper-
ating the Function Selector or a key will turn off the lights in about 10
seconds after the last key operation.
• Hold down
HOLD
to keep the lights on.
Pre-Operation inspection
To avoid the possibility of electric shock or incorrect measure-
ment, check the following items before using the product.
If the operation check reveals any abnormalities, stop the
check immediately and do not use the product.
• For voltage measurement, short the test leads and check that
0 V is displayed.
• For Measuring Resistance or Continuity Check, short the test
leads and check that 0
is displayed.
• Measure a test item with a known value (battery, AC supply,
resistor, etc.) to confirm that the known value can be displayed.

Measurement Procedures
Observe the following precautions to avoid electric shock.
• Do not grip the 3246-60 or test lead between the barrier
and the tip during operation (
See "Parts Names"
).
• Disconnect the test leads from the measurement object
before handling the Cap.
• Always verify the appropriate setting of the Function
Selector before connecting the test leads.
• Disconnect the test leads from the measurement object
before switching the Function Selector.
• Never apply voltage to test leads when the Resistance,
Continuity or Diode Check functions are selected.
Doing so may damage the product and result in per-
sonal injury. To avoid electrical accidents, remove
power from the circuit before measuring.

Notes*1
To prevent an electric shock accident, confirm that the white
portion (insulation layer) inside the cable is not exposed. If a
color inside the cable is exposed, do not use the cable. Using
the instrument in such conditions could cause an electric
shock, so contact your dealer or Hioki representative for repair.
Periodic calibration and inspection is necessary in order to
ensure that this product operates according to its product spec-
ifications.
Voltage Measurement
• The maximum input voltage is 600 V DC/ 600 Vrms (sin)
or 3x10
6
V•Hz. Attempting to measure voltage in excess
of the maximum rating could destroy the product and
result in personal injury or death.
• To avoid electrical shock, be careful to avoid shorting
live lines with the test leads.
• For safety, test lead connections must always be made
at the secondary side of a circuit breaker.
• The maximum rated voltage between input terminals
and ground is 600 V DC/AC. Attempting to measure
voltages exceeding 600 V with respect to ground could
damage the product and result in personal injury.
Resistance Measurement
Continuity Check
1.
Move the Function Selector to the
V
position.
To select DC or AC (
), use the select
button. (During manual ranging, press the
select button for at least 1 second.)
2.
Connect the test leads to the measurement
object, and read the indicated value.

lights up)
(During manual ranging, press the select
button for at least 1 second.)
Diode Check
When the diode is connected in the forward direction, the dis-
play shows “- 0 0 - ” with a beeping sound.
(When the forward voltage is out of the 0.3 V to 2.0 V range,
the results may be incorrect.)
When connection is reversed, the display shows “- - - - .”
If displays for both directions are the same, the following may
have occurred:
• The diode has malfunctioned.
• The forward voltage of the diode is out of the measurement range.
Replacing the Batteries
• To avoid electric shock when replacing the batteries, first
disconnect the test leads from the object to be measured.
• Before replacing the batteries, make sure that the Func-
tion Selector is OFF.
• Be sure to insert them with the correct polarity. Other-
wise, poor performance or damage from battery leakage
could result. Replace batteries only with the specified
type. (Coin-shaped lithium battery CR2032)
• After replacing the batteries, replace the cover and
screws before using the product.
• Keep batteries away from children to prevent accidental
swallowing.
• To avoid the possibility of explosion, do not short cir-
cuit, disassemble or incinerate batteries.
• Handle and dispose of batteries in accordance with
local regulations.
2.
Connect the test leads to the measure-
ment object. When the continuity (thresh-
old: 50±40
or less) is established, the
beeping sounds.
1.
Move the Function Selector to the
position and press the select button
twice.
