Software for the Model PW3336/PW3337
The latest firmware version is as follows.
This version upgrade contains an enhancement of the harmonic measurement performance. Refer to Version Upgrade History below.
Before you proceed
Please check the version number of the firmware that is displayed along with the model name of the product to the LED display when the power is turned on the PW3336/PW3337.
Version Upgrade History
V1.22 (May 2015) Newest Version
1. The occurrence frequency of the lighting-up of the HRM ERROR lamp, which indicates that an error occurs during a harmonic measurement, resulting from measurement gaps is reduced from up to 40% (during measurements at 45 Hz) to 0% during harmonic measurements at a fundamental frequency within the following ranges:
45 Hz and more but less than 50 Hz
56 Hz and more but less than 60 Hz
V1.21 (February 2015)
1. GP-IB communication connection issues.
2. When sending commands exceeding 1024 bytes via GP-IB, the PW3336/PW3337 would hang or freeze.
3. Despite sending the HOLD RESET command during integration, a device dependent error was not issued.
4. Requests to change the display item using the command “:DISP:MODE” could not be actioned.
5. Corrected the response to invalid addresses sent using the command “:IP:ADDRess”.
6. GP-IB serial poll operation issues
7. When using the command “:DATAout:ITEM”, commands other than those that can be specified by this command are now cleared.
8. GP-IB controller settings not supported by the hardware have been corrected.
V1.20 (November 2014)
1.Displayed voltage values that are acquired by measuring PWM waveforms output from secondary sides of inverters and converted by the average value rectified RMS converted value method (Umn) are improved to the same level as those measured with other power meters.
The characteristic improvement will not affect any accuracy specifications.
1.During average operation, starting integrations brought average values to zero.
2.During communications via RS-232C, pressing repeatedly the LOCAL key stopped instrument operation.
3.During the display hold, switching the display between the normal and the harmonic with the communications commands disabled the display hold.
1.The communication processing via LAN, RS-232C and GP-IB is standardized to that of HIOKI Model PW3335 Power Meter (launched in September, 2014).
V1.10 (December 2013)
1. Added 100Hz/5kHz to the frequency range.
1. During GP-IB communication, when one row of commands is significantly long (for example, when multiple commands are strung together in one row), there may be error in recognizing the commands.
2. During integration, before starting the integration calculation function, the start timer behaved abnormally.
3. In key lock state, remote control over a LAN was also made invalid.
4. When using the MODE command for the 3331 Power HiTESTER to specify a 3-phase line, 3P3W2M was specified for the wiring of the PW3336/PW3337.
5. When querying the display state using the ”DISP: MODE?” command after changing the display using the HRM key, a response different from the true response was returned.
6. During LAN communication, when closing the port immediately after sending a settings command, the settings command could not be processed.
7. After starting Averaging, prior to displaying the first average value, the efficiency display showed o.r. This has been fixed to show the instantaneous value.
V1.00 (June 2013)
