FEATURES

● Separate amplifier-type pressure sensor

Faster response is achieved by reducing the total capacity of piping.

● Two-color, LED digital display

High-intensity, two-color LED ensures high visibility. Four types of

display patterns are selectable.

● Chattering prevention function

The instantaneous drops in base pressure due to the activation of a

large-bore ejector or other devices can be canceled. This eliminates

the need for preparing a sequence program.

● Automatic sensor head recognition function

When the power is turned on, the amplifier checks the sensor head

connection automatically. A recognized sensor head type appears

green on the display for 0.5 seconds.

● Industry's smallest and lightest sensor head (AP-41M)

This sensor head with half the volume of conventional models

weighs only 4.8 g, enabling flexible mounting.

● High-resolution mode (AP-40RA)

The resolution can be multiplied temporarily by 10 to stabilize

detection of minute differential pressure.

● Zero-shift function (AP-40RA, 40ZA)

The current pressure value can be reset to 0 at any time in order to

prevent measurements from being affected by fluctuations in base

pressure.

MOUNTING BASIC OPERATION ■ AP-40A/40RA/40ZA Basic operation (See also "ADJUSTMENT" on page 4.) ● Checking the suction condition 1. Select F-3 (2-independent mode) and return to the measurement mode. As shown in the figure with "Amplifier accessories" on page 1, attach the mounting bracket to the amplifier with hexagonal socket bolts. The mounting bracket can be attached laterally according to the location. CAUTION ➮ Refer to the setting in "Operation Mode" on the left-hand side of page 4. 2.

OTHER FUNCTIONS OPERATION MODE SELECTION ■ Zero-shift function (AP-40RA/40ZA type only) ■ Auto-tuning mode (F-1) The zero-shift function is used to reset the current pressure value to “0” using an external signal input, in order to prevent measurements from being affected by fluctuations in base pressure. Using the AUTO key, detect the upper limit value (A) and the lower limit value (b). The detection level (C) is automatically set at the midpoint between the two values.

ADJUSTMENT Measurement mode ▲▲ ▲ ■ Operation Mode ■ Preset Value Input Mode Determine the desired operation mode. (➮ Refer to “OPERATION MODE SELECTION” on page 3.) Determine the preset values. ● Auto-tuning mode (F-1) 1. In measurement mode with the current measured value displayed, press . The AP-40A enters the preset value input mode. 2. “A” and the current preset value flash alternately. 3. Position the target at the desired upper (lower) limit. The current operation mode is displayed.
