includes information

for both the CSA and

CSA/ATEX certified

versions of the
BetaGauge PI.

1. Introduction

The BetaGauge PI Reference Class (PIR) combines the high
accuracy of digital electronics with the convenience and ease of
use of an analog test gauge. Accurate to ± 0.04% of reading, the
BetaGauge PIR can be used as a calibration reference, or in any
application where high accuracy pressure measurement is
required.

Many user configurable functions have been designed into the
BetaGauge PIR including sampling rate, TARE, damping, auto
shut off, and min-max. Once the gauge is configured, settings can
be locked and password protected to prevent unauthorized
changes to configuration.

1.2 Standard Equipment

Check to see that your BetaGauge PIR has arrived intact. Batteries
are factory installed unless you have purchased the optional 24V
powered version, in which case batteries are not supplied or
installed. Save the packing materials at least until you have
verified that there is no concealed damage.

1.3 Safety information

A Warning identifies conditions and actions that pose hazard(s) to
the user; a Caution identifies conditions and actions that may
damage the Calibrator or the equipment under test.

Special Conditions for Safe Use:

Misuse

Should the BetaGauge PIR be exposed to overpressure or
sudden physical shock (i.e. being dropped) it should be examined
for any damage that may cause a safety concern. If in doubt
please return the unit for evaluation to Martel Electronics. Please
refer to the Customer Service Section for contact information.

WARNING

The Beta Gauge PIR is not intended for use with flammable
substances and is intended for installation only in locations
providing adequate protection against the entry of solid foreign
objects or water capable of impairing safety.

Caution

To avoid possible damage to calibrator or to equipment

under test:

• If the message changes to “OL” the range limit is exceeded and
the pressure source must immediately be removed from the
BetaGauge PIR to prevent damage to the pressure transducer
inside.

• Maximum torque allowed is 13,5 Nm = 10 ftlbs. NEVER exceed
the torque allowed.

3. Operation

Power: The standard BetaGauge PIR is supplied with 3 AA
batteries installed. If you purchased the optional 24Volt powered
version, batteries are not installed. Connect a 24V power supply to
the terminal block on the rear of the gauge, noting proper polarity.
Do not install batteries when external power will be used.

Push the power button momentarily to turn the unit on. Push it
again to turn it off.

Set-up and configuration:

Push the CONFIG button to access the user-settable functions on
the gauge. Each time the CONFIG button is pressed; the display
advances to the next function. Once a function has been set,
press ENTER to exit the configuration menu, or CONFIG to
continue with further configuration. In order, the configuration
menu and operation is as follows:

1. Engineering Units set. The unit is shipped configured to

display PSI. By pressing the ▲ and ▼ (ZERO and MAX/MIN)
keys you can scroll forward and backwards through the 18
standard engineering units plus a one custom unit/scale.
When the desired unit is displayed, press ENTER or CONFIG.
Pressure will now be displayed in the chosen engineering
units.
See the Specifications section of this manual for a list of
available engineering units. See the Supervisory Mode section
for details on setting up custom units.

2. Set Auto Off. The auto-shut off can be set in 1 minute

increments from 1 to 30 minutes or “off” (continuous
operation). The unit is shipped set for 30 minutes. Use the ▲
and ▼ keys to set the desired interval. The “off” setting is at
the low end of the choices, below 1 minute.

3. Display battery voltage. Actual voltage and a percent of life

bargraph indicate battery condition

4. Display actual temperature. The BetaGauge PIR is

temperature compensated, this displays the temperature
measured by the internal sensor. The value can be set to
degrees F or degrees C using the arrow keys.

5. Set damping. Choices are “on” and “off” set with the ▲ and

▼ keys. Turning damping on will smooth readings from
pulsating pressure sources.

4

6. Set sample rate: This determines how often pressure is

sampled and the display is updated. Choices are 0.5, 1, 3,
and 10 samples/second. Note that 10/sec provides the fastest
response time.

7. Set TARE. This allows you to set a constant offset value,

which is then subtracted from the measured pressure. For
example if a TARE is set at 30 PSI, and the measured
pressure is 37 PSI, the displayed value will be 7 PSI.
A pressure of 27 PSI would be displayed as –3 PSI.

The tare value is set manually with the ▲ and ▼ keys, and is
based on the engineering units and resolution selected for
display. TARE value can be set to the maximum range of the
gauge.

The bar graph will always display the actual pressure based
on the full range of the gauge regardless of the tare setting.
This is done for safety to insure that even with a “0” reading
that pressure is being applied to the gauge.

8. Function Lock: Access to each of the settable parameters

above can be turned “off” once set, to prevent unauthorized
changes to configuration. This is accomplished through a
password protected “supervisory mode”. Press ENTER to
access the supervisory mode, or CONFIG to return to normal
operation.

4. Supervisory Mode

Press ENTER when “FUnC LOCK” is displayed, 0PWRD will be
displayed on the gauge. The password to enter supervisory mode
is 101, set using the ▲ and ▼ keys. Holding a key continuously
will cause the display to advance more quickly for faster setting.
The password is factory set and cannot be changed

1. Your BetaGauge PIR is shipped from the factory with all
setting access “unlocked” or available to be changed.

2. In supervisory mode each of the parameters can be locked or
unlocked using the ▲ and ▼ keys. Select LOC (lock) for
those parameters you do not want to be accessible, and
UnLOC (unlock) for those can be accessed.

3. In order, the functions that can be unlocked, locked or
accessed are:

• Zero function (enable/disable)

• Set pressure units (enable/disable)

5

• Auto shutdown adjustment (enable/disable)

• Damping settings (enable/disable)

• Sample rate setting (enable/disable)

• Tare setting (enable/disable)

• Custom engineering units (set scale factor)

4. Use the CONFIG key to scroll through the above choices, and
the ▲ and ▼ keys to lock and unlock features. Press CONFIG
to continue scrolling through the parameters, pressing ENTER
at any point saves your settings and returns the gauge to
normal operation.

When a function is “locked, it cannot be accessed or changed
from its current state. To change a locked function, enter the
supervisory mode, and unlock the function. Once it is
changed, you may enter supervisory mode to lock access
again.

5. Setting a custom engineering unit or scale: The last menu
choice in supervisory mode is SET FACTR. This allows you to
set a multiplier factor from 0.001 to 100, creating a custom
scale. The set factor will be multiplied by the PSI measured,
the result will be displayed.

For example: 40 PSI is the equivalent of 1000 lbs of product
in a tank. You want to display the product weight , using a
100 PSI gauge. By setting a factor of 25, a 40 PSI pressure
would display as 1000 (40 x 25). The engineering unit
displayed on the BetaGauge PIR will be “Cust”.

5. Normal Operation

Turning the backlight on and off: Press the ENTER button.

Zeroing the display: Press and hold the ZERO button.

MAX/MIN: The BetaGauge PIR stores minimum and maximum

pressure values in memory. Pressing the MAX/MIN button once
will display the minimum pressure from memory. Pressing the
MAX/MIN button again will display the maximum pressure from
memory. After about 2 seconds, the gauge returns to normal (live
display) operation. To clear the MAX/MIN memory registers, press
and hold the MAX/MIN button for 2 or more seconds until “CLr” is
displayed.

The analog bar graph at the bottom of the display indicates the
applied pressure level relative to the full range of the gauge. Keep
in mind that if a TARE value has been programmed into the
