TelePole WR/ Operating & Maintenance Manual Page 9

3. Operating Instructions

3.1. Preparation for Use

Remove the instrument from the shipping container and check for any physical damage. In

the case of damage, report it immediately to MGP Instruments.

Do not attempt to install or operate damaged equipment since safety and performance may

be affected

3.2. Starting-up

Ensure that the detector is connected to the meter. Press the ON/OFF push-button. For pre-

1999 models, when the meter is turned on, it carries out a short self-test procedure indicated

by displaying all the segments on the display and emitting two beeps for a short period.

Following the test, the meter is ready for use. For 1999-present models, when the meter is

turned on, it emits a single beep, then followed by three shorts beeps indicating the self-test

procedure is completed and the meter is ready for use.

Note: When the meter is turned on, the low range GM Tube is not connected. As a safeguard,

the high-range GM Tube is connected (>600 mR/hr) in the event that the user is in a high

exposure rate field. If the radiation field measurement is lower than 600 mR/h, the meter

switches to the low range GM Tube.

3.3. General Functions

3.3.1. Exposure rate Display

The TelePole measures Exposure rates in the range of 0.0 1mR/h to 999 R/h.

Readings are displayed in digital and analog mode. The ranges in the bar graph are changed

automatically and the units displayed correspond to both, the digital and analog display. The

bar graph measuring response is quicker than the digital display response since the latter

averages the readings.

3.3.2. Automatic Range Switching:

The detector includes two Geiger: Low range - ZP-1201 (or equivalent), and high range -

ZP-1301 (or equivalent).

In a field of 0.01 mR/h to 800 mR/h both geigers are connected and the field is measured by

the low range geiger. In case the radiation field is higher than 800 mR/h (Optional Firmware

‘070301’ 2500 mR/h), the low range geiger is disconnected, and the radiation field is

measured by the high range Geiger. The switching between the low and high range geigers

is done at 800 mR/h when the radiation field increases (low range geiger is disconnected),

and at 600 mR/h (Optional Firmware 2000 mR/h) when the radiation field decreases (low

range geiger is connected).
