Pre-Operation Inspection
Before use, inspect the instrument and verify that it is
operating properly.
See: Instruction Manual "2.1 Pre-Operation Inspection"
The insulation of the power cord and test leads is not
broken. No metal is exposed.
No evident damage to the instrument.
When turning power on
The STANDBY key lights up in red or green.
After the completion of the self-test (when the model
number is shown on the screen), the Measurement
screen is displayed.
Measurement Process
1
Inspect the instrument before the
measurement.
2
Install a multiplexer unit.
(RM3545A-2 only; as necessary)
See: Instruction Manual "2.5 Installing the Multiplexer
Unit"
3
Plug the power cord into the power outlet.
4
Connect measurement leads to the
measurement terminals.
(When using a multiplexer unit,
connect the connector.)
5
Connect the temperature sensor or infrared
thermometer.
(When using the temperature correction
function or ΔT)
6
Connect the external interface.
• LAN, USB, or RS-232C
• EXT. I/O
• D/A Output
• The printer
7
Turn on the instrument and cancel the standby
state.
The STANDBY key will change from red to green.
Main power switch: Rear
ON( )
To obtain precise high-accuracy measurements,
provide about 60 minutes warm-up after turning power
on.
8
Check the measurement target.
Weld resistance, Signal contacts, Power contacts,
Temperature-rise test, etc.

Make instrument settings.
• Measurement range
• Measurement speed
• Settings in accordance with the measurement target
To carry out proper resistance measurement, change
the measurement conditions appropriately according
to the measurement target. (Low-power mode,
measurement currents, TC/ ΔT, OVC, pure resistance
mode, contact check, etc.)
See: Instruction Manual "3 Basic Measurements" and
"4 Customizing Measurement Conditions"
10
(as needed) Perform zero adjustment.
• Always perform zero adjustment in the 2- terminal
measurement.
• Zero adjustment is not required for the four-terminal
measurement.
• If the OVC function is set to on, the zero point
adjustment is included in the correction and zero
adjustment is not required.
11
Perform measurement.
Connect the measurement leads to the measurement
target.
12
Check the measured values.
13
When finished measuring, turn the power off.
Use the STANDBY key (by pressing and holding it for
1 s) or the main power switch to turn off the instrument.
(If you press and hold the STANDBY key while the
main power switch remains in the ON position, the
instrument's internal circuitry will remain energized. To
turn off power to the internal circuitry, place the main
power switch in the OFF position.)
