One of two types of load calibrations can be selected:
Actual value calibration and Equal value calibration.
Actual value calibration
By the press machine or the weight that accurate weight can be confirmed, add the fixed load to Load
cell of CHECKMAN. Then, you register the value of the power in the measurement device of
CHECKMAN.

Equal value calibration
To perform an equal value calibration, you need the latest data for the load cell that you will be
using. Inputting the value of Rated Output and Rated Capacity on the calibration certificate of the Load
cell, the measurement device computes amplification rate automatically and completes the calibration
operation.

FOR YOUR INFORMATION
1.Specifications
Type of load cells that can be connected Either 350 or 700 ohm types
Recommended input voltage 10V±0.3V(When 350 ohm type load cell connected)
Range of zero position adjustment Approximately within ±0.3 mV/V
Range of amplification rate Approximately 1.2 mV/V through 2.6 mV/V

2. Display of the user settable items
In the setting mode, each of the user settable item names will be displayed in the Lower-limit
display, in alphabetical order, and the current value for that item will be displayed in the Digital
load display. The decimal point will flash.
The "Digital load display" displays numbers and letters. When it displays four digits, a decimal
point will flash next to the digit which can be specified at that time. On the following pages, the
use of each digit is described as follows.

FOR YOUR INFORMATION
Press the key while holding down the key. The Lower-limit display will show the word "
." This means you have to select a setting mode. There are four modes, "", "", "", and
"". The table below describes each. ("" is selected when the system is delivered.)
MODE FUNCTIONS
 ①Modify and store upper and lower limit comparison values.
②Select a different pair of upper and lower limit values.
 ①Load calibration mode.
 ①Select a measurement mode (peak value mode or end value mode).
②Enter the power supply frequency(50 or 60 Hz).
 ①Prohibit making entries or changes to the settings. (You can still view the values
of the pairs of upper and lower limits.)

Connect the load cell cable to the 5P connector on the back of the CM-5
housing, and lock it securely in place. Then, flip the lever of Power switch up
to the power ON. Do not add the load to the load cell until the direction.
1. Press and hold the and keys for approximately three seconds. (Press the key, first.) ---

6. Add the fixed power to Load cell of CHECKMAN.
By the press machine or the weight that accurate weight can be confirmed, add the fixed load to Load cell of
CHECKMAN. We recommended. the load very close to the rated capacity of the load cell. Even if it is the
worst, 55% of the rated capacity must be required.
