USING THE SCALING FUNCTION
When setting the scale value, be sure that the set value
satisfies this equation: set value "max. value – scale value."
(If the scale value is 1,250, then 999.999 – 1,250 = 998,749
max.)
■
CHANGING SET VALUES
When changing the set value while the counter is operating, an
output will be produced if the set value ever equals the present
value. To avoid triggering the output, begin by incrementing a
higher digit to a large number.
■
OPERATING ENVIRONMENT
Although the front of the counter resists water and oils and can
be used where subject to these, extended exposure to large
amounts of either can adversely affect internal components.
The counter, input signal lines, and the input device must be
separated as far as possible from any sources of electrical
noise, such as high-voltage power lines. Shielded input signal
lines can also be effective in suppressing noise.
To prevent damage, the exterior of the counter must not be
exposed to organize solvents (e.g., paint thinner or benzene),

SELF-DIAGNOSTIC FUNCTIONS
The following displays appear when irregularities occur. When
the problems causing these conditions have been cleared, the
present count value and all outputs will be reset in the same
way as when the Reset key is pressed.

minimum value in the H7BR-C (

OUTPUT DELAY
The following table shows the delay from when the present
value passes the set value until the output is produced. (The
delay is the result of output control time, signal transmission
time, relay switching time, etc.)

actual measurements under operating conditions.

BATCH COUNTER MAXIMUM COUNTING
SPEED
The maximum counting speed of the batch counter is 1 kcps.
The batch counter counts the number of completed counts to
the set value for single preset models and to the set 2 value for
double preset models. Operate with a count taking at least 1 ms.
■
OTHER
Always isolate the counter from external circuits or short all
terminals before measuring dielectric strength between electric
circuits and non-charged metal parts or performing similar
testing with the counter mounted in a control panel. This is to
prevent internal circuit damage that might occur if the test
voltage enters the counter interior due to withstand-voltage or
insulation failure in control panel devices.
The counter contains a non-replaceable lithium battery, and
must not be incinerated. Dispose of the counter as a non-
combustible item.
