thoroughly and use the Meter correctly.
● Keep this INSTRUCTION MANUAL carefully and refer to this
when necessary.
● Connect/disconnect the probe after surely confirming the
power OFF. It causes out of order.
● In the event of any doubt arising, the original INSTRUCTION
MANUAL in Japanese is to be final authority.

●Indicating function by kana
When the Meter is delivered, the Meter is set with LCD display/printing mode by alphabet.
But the Meter can be converted to LCD display/printing mode by kana.
By pressing the [Clear] key ⑬and [Cancel] key ⑫simultaneously, display and printing mode are converted.
By pressing these two keys again, the mode returns to the mode by alphabet.
Converted mode is remained even after power OFF.
So in case the Meter power ON next time, the Meter can be used with the converted mode at previous
power OFF condition.

５．MEASUREMENT
5‑1 Preparation for the measurement
1. Connect the probe suitable for an object (wood, paper, mortar and plaster) to be measured.
2. Power switch ⑤ON and confirm the indications on the LCD display ⑰.
For wood ＝[TG-H] For paper ＝[KG] For mortar and plaster ＝[MORTAR]
Example: In case of connection
of the probe for wood
★When the probe is not connected, probe error [PE] is indicated on the LCD display ⑰and the power
OFFwith3beepingsounds.
★When [PE] is indicated on the LCD display ⑰and power OFF with 3 beeping sounds though the
probe is connected, power ON again after 2 to 3 seconds.
★When [PE] is still indicated on the LCD display ⑰in spite of power ON again after 2 to 3 seconds as
above mentioned, it seems that the probe is out of order.
Please contact to the purchased agent or our sales office to repair.
★When the power switch ⑤ON keeping on the probe pressing against the object to be measured,
once [LLL] is indicated on the LCD display ⑰and the measured value is indicated in 3 to 4 seconds.
3. Press the「Group」key ①, select the mode suitable for the object to be measured.
Refer to 5‑2 Converting the measurement mode on page 16.
4. Press the electrode with a constant force against the object to be measured and read the indicated value
after settlement of the indication.
When the 2-needle electrode is used, thrust it to an object to be measured.
5. When the hold key ②is pressed, the indication on the display will be held at the time just removing
the electrode from an object to be measured.
Refer to 5‑3 Converting the hold mode on page 17.
Hold mode is released by pressing the hold key ②again.
※Note: In case the measurement is carried out with the probe hammered into the wood which is
an object to be measured:
Keep on the hold mode releasing until completion of the hammering of the probe.
Pay attention to convert the mode to the hold mode at the time when the measured value is read
after completion of the hammering.
(Whenthehammeringiscarriedoutinholdmode,it causes measurement error as the data during
hammering is held and indicated.)

5‑12 Releasing the communication with PC and printing out
For releasing the communication with PC, refer to item "5‑10".
For releasing the printing out, refer to item "5‑8".
5‑13 Setting the memory mode
MR-300 can store up to Max. 15,000 data in the memory mode.

memory block.
The construction of the memory can not be changed on the way of the measurement.
Restore the construction of the memory and reset as shown in item "5‑14".
1. Fixed block system
5 blocks fixed system (3,000 data/1 block)
2. An arbitrary block construction system
This is a system to set the numbers of memory block and block size(numbers of the data storing
in 1 block) within Max. 15,000 data arbitrarily.
Max. number of the memory block will be 1,100 blocks and Min. of block size will be 10 data.
Memory can not be additionally constructed on the way even though the memory capacity is not full.
①Setting the fixed block(Memory block: 5, Number of memory: 3,000)
◇Confirm the ON condition of the hold mode before pressing the key
Mem. [Mem: Fixed Block] and [G:User's format Block] are indicated on the LCD ⑰.

Mem. (Construct the fixed block) [Mem: BLK.1 No.---] is indicated blinking on the indicating
part of the memory condition.
↓←Cancel (When the setting is suspended)
Set The setting of the fixed block is finalized and blinking on the LCD stops.
[Mem: BLK.1 No.0] is indicated and the measurement can be done in the memory mode.
●Before measurement, confirm the measurement mode, press the [Group] key ①and change the mode
if necessary. After measurement, the block mode can not be changed.
②An arbitrary block construction system(Memory block × No. of memory ≦15,000)
◇Confirm the ON condition of the hold mode before pressing the key.

●Before measurement, confirm the measurement mode, press the [Group] key ①and change
the mode if necessary. After measurement, the block mode can not be changed.
※When the stored numbers in the memory reach the Max. data numbers while measuring in the memory
mode, the data is stored in the next empty block.
In case the data exist in the next block, the data will be stored in the third empty block.
If there are no empty block to store, the message [Memory Overflow] is indicated on the LCD ⑰and
the memory mode of the measurement is released.
