Monitor Mode

Step 1. Press the Mode buon to get to the Monitor Mode screen. (See Fig. 5-6)

Step 2. Press the CURSOR buon unl the Transducer type is ashing.

Step 3. Press the Select buon to select the Transducer Type Under Test. The

choices are:

• ACCEL (Accelerometer)

• VELOCITY

• DISPLACEMENT

Step 4. Press the CURSOR buon unl the M 0.0 (Mass) is ashing.

Step 5. Use the key pad and enter the weight of the transducer in grams if known. (See Appendix B for

Transducer Weight Guide) If you do not enter a weight, 20 grams will automacally be used to correct

for the eects of transducer mass loading.

NOTE: When a velocity or accelerometer adapter plate is used, add 103 grams to the transducer mass.

NOTE: When entering values from the keypad, remember to enter the value and wait a few seconds

unl the cursor advances to the next posion before trying to enter another alphanumeric character.

You will also have to press the selected key pad buon once for numbers and twice or more for let-

ters.

Monitor Mode Tesng

Step 1. Press one of the FREQUENCY RANGE buons (See Fig. 5-1) to select the range you want to use

for the test:

• 3-100 Hz

• 100-1000 Hz

• 1000-10000 Hz

Step 2. Unlock the Frequency Knob and adjust to the desired frequency for test.

Step 3. Press the RUN/STORE buon to turn on the shaker. Make sure the red LED light is on to indicate

that the shaker is operang.

Step 4. Unlock the Amplitude Knob and adjust to the desired Amplitude.

NOTE: It is important to note that the HI-803 has microprocessor controlled monitoring and supervi-

sory limits built into the instrument as follows:

• Vibraon frequency or amplitude is out of recommended operat ing range - the display

ashes the frequency or amplitude elds. Adjust the shaker to within operang limits. (See

Table 5-2)

• Vibraon amplitude at lower frequencies have exceeded 0.1 inch (2.54mm) PK-PK displace-
