GENERAL INTRODUCTION

Thank you for selecting the PTM1 Temperature Meter. The PTM1 is
a precision tool that measures temperature. A built-in
microprocessor stores, calculates and compensates for K, J and T
type thermocouple probes.

This unit has a waterproof IP67 case. The touch mode keys are
highly reliable with tactile and audio feedback. This meter uses four
“AAA” batteries. The resetting of parameters are not required when
power is restored.

The front of the meter has a large LCD that displays temperature
and time/date simultaneously along with user prompts and
thermocouple type indicator.

The unit is also equipped with a non-volatile memory allowing the
user to store 50 different sets of readings. This unit will assign a site
number for each set of readings stored, so the user can review the
data easily.

Other features include long battery life and 50/60Hz AC noise
rejection. This meter is user-friendly for field, industrial and
laboratory applications.

INITIAL INSPECTION

Carefully unpack the unit and accessories. Inspect for damages
made in shipment. If any damage is found, notify your Physitemp
representative immediately. All packing materials should be saved
until satisfactory operation is confirmed.

WATER PROOF

Though the PTM1 meter is housed in a watertight case, DO NOT
use it underwater. The watertight case prevents permanent damage
to the unit if accidentally dropped into non-corrosive solutions.
Follow these steps immediately if the unit is immersed in any
solution:

1. Rinse unit carefully with distilled water. After rinsing and drying,
inspect and clean connectors to remove all contaminants that
may affect probe connections.

2. Wait for the unit and probe to dry completely before resuming
operation.

3. If the unit does not function correctly after steps1 and 2, call
Physitemp for possible repair or replacement (see Warranty).

5

INSTALLING THE BATTERIES

The PTM1 meter is supplied with four “AAA” alkaline batteries
required for operation. To insert the batteries into the meter, follow
the procedure outlined below.

1. Use a screw driver to remove the two screws and battery cover

to expose the battery compartment. (Figure 1.)

2. Note the polarity and insert the batteries into the battery

compartment correctly.

3. Replace the battery cover and make sure to secure the two

screws for the water-tight feature.

[Note: Press the [ON/OFF] key to turn the unit on. If the unit is
running then you can press the [ON/OFF] key to turn the unit off.
The unit will automatically turn off after 30 minutes of no key
activity.]

MODEL PTM1 MODES

A. MEASURE mode

When user powers on the model
PTM1, the MEASURE mode screen
will appear. The instrument will
return to this mode once you exit
from other modes. Only in the
MEASURE mode, the user can
press the [SAVE] key to save the

into the next available slot of the 50-slot memory.

temperature reading, time and date

The user can clear the MIN and
MAX values while in the MEASURE
mode. The instrument will display
the screen on the left for a few
seconds when the user presses the
[CLEAR] key.

The user can turn on or turn off the one hour-auto shutdown
feature only in the MEASURE mode. Press the [HOLD] key
and hold for 10 seconds to toggle the setting of the one
hour-auto shutdown feature.

B. MAX mode

Press the [MAX/MIN] key in MEASURE mode to enter the
MAX mode, the model PTM1 will display the maximum

temperature reading it has captured since the last time the
instrument has been cleared. The instrument will display 2
screens, one with time and the other with date. The user can
press the [CLEAR] key to clear the MAX and MIN values while
in this mode.

C. MIN mode

Press the [MAX/MIN] key in MEASURE mode to enter the MIN
mode, the model PTM1 will display the minimum temperature

reading it has captured since the last time the instrument has
been cleared. The instrument will display 2 screens, one with
time and the other with date. The user can press the [CLEAR]
key to clear the MAX and MIN values while in this mode.

D. HOLD mode

Press the [HOLD] key in
MEASURE mode to enter the

SPECIAL NOTE WHEN SETTING I N REL TIME

The Instrument will auto shutdown after 1 hour of no key activity
unless the user turns off the auto shutdown feature (see [HOLD]
key function). The maximum elapsed time the instrument can
record is about 24 hours “23:59:59” after which it will start back
to “00:00:00”. If the user turns on the instrument after shutting
down for a long period of time, the instrument will still compute
the elapsed time from the last [CLEAR] key function the user
performed.
Example: If the user clears the min/max at 03:00:00AM and the
last max recorded occurred at 04:00:00AM the next day (after
more than 1 day) the recorded elapsed time will be 01:00:00.

e. °C / °F

Press the [UP] or [DOWN] key to

change to °C or °F. This will set the

Flashing

default turn-on temperature unit.

f. TYPE K, J or T

switch to the RECALL mode. Press the [LEFT/RECALL] key
again to exit the RECALL mode and return to the MEASURE
mode.

When the instrument switches to the RECALL mode, it will first
display the last data saved by the user. Three screens will be
displayed for every data site.

The first screen will display the site number, the 2nd screen will
display time and the 3rd screen will display the date. The
temperature reading saved is always displayed in all screens.
